 Posted: Tue, 25th Dec 2012 01:50 Post subject: Upgrading from a first gen i5 , need some advice |
|
 |
Hey guys,
ever since getting my new ram i've been getting the overclock itch, now my current board doesnt support it in any way, and no more 1156 boards to be found around here.
sooo leaves the option of upgrading, got a decent offer on my old set so been thinking about it alot the past few days. Havent overclocked anything sans a gpu since the days of athlon xp's lol so its all pretty rusty.
Would love some advice on a few matters from you guys=)
I have to do with a somewhat limited budget so this caught my eye so far.
2500K (really only way to go I hear)
along with a
Asrock Z77 Pro4 (I want a board with 2 pci-e lanes, this one seems very nice, decent features decent overclocking with unlocked multiplier for a very decent price)
I Currently have a first generation (1156) lynnfield i5 - 750 it runs at about 2.9/3 ghz.
First question, also the most important one imo. How big of an upgrade would the 2500k be relative to the 750? Is it a decent upgrade even at stock speeds or will I have to overclock it to get more performance out of the cpu than I get now?
2nd, do you guys reckon the z77 pro4 is a decent board? Im looking for a board around 100 euros that has decent overclocking capabilities, will last me a while(good components etc) has sata 3 and supports sli.
3rd. I plan to someday upgrade to a sli setup(more likely ill just get a single card that outperforms this card in sli lol, but one can dream). until that time comes though I have an old gtx 280 here, its dissassembled atm but would it be worth putting that back together to use it as a dedicated physx card?
Thanks for reading guys, hope you can help me out

I'd save my money and grab the next gen in 2013 tbh.
Yes, yes I'm back.

When will that be coming, and can I get a set for around 300 euros thatll beat a 2500k set? figured that would be way out of my budget
the added problem of waiting is that the set I have now will be worth less alot quick I reckon
found this on the haswell wiki :
Performance
Compared to Ivy Bridge (expected):
At least 10% CPU performance increase.[6]
Double the performance of the integrated GPU.
theres that. but oh hell I just read this is going to be socket 1150, yet another one.. the hell these change quick these days. Reckon I'd be better off waiting then if I want to be somewhat future proof?

Well, saving the money means you'll have time to make some more on top of it. New sockets that will be the new industry standard for some time, you can get a lower tier CPU to start off with so you only have to upgrade the CPU.
You get a 2500K you'll be stuck with tech that's already dated.
Yes, yes I'm back.

"Well, saving the money means you'll have time to make some more on top of it."
I wish it worked that way lol. Got some money now, but by the time haswell is out itll be gone or quite a bit less. On top of me getting less for the current set.
and now with this 1550 it just baffles me, we getting 1140 in 2014?
I certainly dont want to upgrade twice, and getting a lower tier cpu probably means downgrading from the i5.
whatll be so much better about 1150? the 10% increase seems hardly worth the trouble and wait.

Haswell is supposedly coming at end of April. That's the information for now.

Wait for Haswell. You'll probably be buying a good system towards the end of next year when prices settle.

You guys keep saying that.. but why? What makes the 1150 platform/haswell so much better?
if I buy a haswell next year itll be superseded by skylake the year after, so future proofing seems undoable these days anyway. and I really dont want to wait a year for prices to settle on chips that only perform 10/20% better, so is there anything im missing?

You seem to want upgrade, so why ask whether you should upgrade? If you can wait for the next generation, wait for it since you already have a very capable CPU. If you want to upgrade now, do it.
The Z77 pro4 is a great board and the 2500K will net you a decent boost.

well I do want to upgrade, A decent 1155 upgrade would only cost me around 100/120 atm since i got a decent offer on the current set. I doubt Ill have the same oppertunity when the haswells come out.
but if these hasswells and 1150's are revolutionizing things I'd better hold off. I been out of the loop for a while so not sure why they would be worth the wait, the only thing I can see on the wiki was something about 10% performance increase.
Considering i'd probably be able to overclock the 2500k to 4+ghz, and it being a better architecture and whatnot, could I expect a 30/40% performance increase over my 750? and will the 2500k futureproof me for a year or 2?
Also anyone have experience with using another card for dedicated physx?
goal of the upgrade would be future proofing for 2 years or so, with a gpu upgrade in a year or so.

2500K will definately last for couple years, especially when overclocked. No point imo waiting haswell to get some 10-20% performance increase (Good example is SB vs Ivy, the so called 10% performance increase could be seen only in diagrams + in exhange you get increased temperatures). Not to mention that you get this upgrade for so cheap, so yeah absolutely go for it. OC the 2500K to 4.5Ghz levels and it will absolutely destroy your old i5 (even stock its much faster).
I have used GTX 460 as dedicated PhysX when i had 670, difference was very big in Borderlands 2.

Great. Hoping this guy's offer will be valid till 20ish january and then ill be able to get the whole set and not have any non pc downtime(could you imagine the horror?!)
Any idea of the 2500K's run hotter or cooler than the 750's? This 1156 cooler i got should fit on a 1155 too, and its pretty decent for this cpu. its a Cooler Master Hyper TX3 ; would that be enough to get a decent overclock and still have decent tempts?(the very lightly overclocked 750 runs @64c at full load)
I see it comes with a iGPU, can you disable this on the bios level and does disabling it have any practical value?

I misunderstood your posts I think, I thought you were asking whether upgrading now would be a good choice.
2500K should run cooler and you can disable the GPU in the BIOS. I'd advise the 3570 (if the 2500 isn't cheaper), because the 3570 is 5-10% faster (I did my own benchmarks) and because you'll get a much better iGPU (why not get it if you can?). As for Ivy being hot, no problem with a good cooler (the i30 costs 30 euros).
edit: there is no way you'll get a 40% boost in performance I think, unless you're comparing a highly OCed 2500 to a stock 750. Keep in mind that while 40% sounds reasonable, it actually is a huge step forward (so very hard to achieve).

Aye heavily overclocked is what I meant. Assume somewhat like a 15% increase @ stock?
ok so the 3570K would be the better choiche then? Its only about 4 euros more then the 2500K Performance is what im after here, but if a properly overclocked 2500k performs better and the 3570s dont like overclocking as much as the 2500's(wierd sentence i know, i blame the wine) i'd be better off with a 2500? the iGPU really doesnt matter to me as ill be disabling it anyway, no reason to keep it enabled if I dont use it.
Do they clock as well as the 2500K's do? and will the TX3 be enough cooling to run it at decent temps or will I have to replace that for an even bigger one?

You have no use for the GPU, really - and as previously mentioned the Ivy-processor runs hotter, you'll make up for those 5-10% easily with some standard overclocking and at lower temperature than the 3570K.
The 2500K is THE overclocking monster. With good cooling it can do a lot of really nice stuff.
Yes, yes I'm back.

From what I've read, Haswell is more about the IGP and power efficiency for notebooks etc. than any major performance increases. I may be wrong but that's what I've gathered from various sources.

Read some reviews which states that they overclock less(and run hotter) but are either on par or a very tiny bit better better than the 2500K. Couldnt find anywhere what the temp difference would be though. I dont plan on running a daily 4.8(or 4.6 on the 3570). Will probably even out around 4.4ish. Considering that wouldnt the 2570 give me a tiny bit more bang for buck?
If that tiny bang also means 20c its a different story though, but im willing to invest in a new/better cpu cooler if its not crazy expensive. What I dont want it a system running higher than 70ish @ load

The problem is the factor luck. I can get my 3570 to 4.8 without doing any tweaking (just using the AI tweaker thingy in the Asrock BIOS), while my friend with a 2500 can't hold it stable at 4.4. I bought a 3570 for my cousin at the same time from the same shop, so I assume it's the same batch, both are stable and relatively cool (75 degrees) with prime at 4.8. So no one can say "X will OC better than Y" since no one can guarantee it (unless you're comparing a chip that overclocks very badly to the 2500/35710). Both will OC fine, it's up to luck how far you can go.
I can only give my personal reasons. Since the difference is so tiny, I went for the newer tech.

I can get my 2500K to 5GHz (booted into windows and browsed a bit, but got way too hot, and it was obviously not prime stable). Stable at 4.9 but too hot for my cooler (planning on getting something like the H80i). For the moment I'm running it at 4.5GHz and haven't really felt any reason to push it any harder.

I am one of those people who got a CPU (2500K) from a "bad" batch. It's only completely stable at 4.3 for me. Any higher and I need to add too much to the Vcore to keep it from BSOD-ing at random times (it's running at around 1.3V at the moment already) and there isn't that much to gain anyway.

1.176 at 4.4Ghz. I don't know how much it actually needs since I haven't tweaked it manually, this is the auto value.

I'll check when I have time, I don't remember the value anymore. The value is indeed very nice since most other brand mobos seem to set it at 1.25 atleast at 4.4.

(Which is plenty enough though, I have not tried to go further in OCing it.)
). Second one was stable with 4.7Ghz @ 1.4V and this one is stable with 1.4V @ 5Ghz (have even ran 3dmark11 with 5.3Ghz 1.55V). Cant wait to test out my new 2700K (probably wont boot over 40x multiplier
