OK, so I got GTX 680 now but I am planning to do sli very soon. I am still deciding if I should go for GPU or CPU though.
My i5 2500k is clocked to 4.2 and doesn't seem to get any higher. Its not good in games like GW2 since my overclock from stock to 4.2 gave me like 30-40 FPS..
But in other games overall, would i5 2500k 4.2 overclock my gtx 680? i would buy i7 3930 middle 2013 otherwise.

AFAIK no game uses the Hyperthreading of a i7 CPU so I'd stick with the i5.
What is your monitor/s resolution?

Well i have two 670 and i5-2500k and i am not getting any bottlenecks at all you will be fine

The 2500k does not bottleneck a 680. What motherboard do you have?

You've never heard of BF3 MP, have you? The i5s can do perfectly fine in this game, but the i7s are superior in it because of Hyper-Threading. All games use it, just not all games use it much on the i7s because of games not using that many threads. i3s let a lot of games use Hyper-Threading.

While it's not common, there are a few games that will, but you normally only gain 10% more FPS as a result. Metro 2033, Resident Evil 5 also use the hyperthreading and gain about 10% more FPS as a result. As the above poster stated, BF3 uses it too, but I don't have that one.

z77-v pro soon. Planning to buy it with my 2nd gtx 680. Support from my shop told me that I needed a 850w gold PSU also.. I was planning for 750 since the recommended from gtx 690 is 650.. But what do you guys suggest there?

It depends on the PSU. The wattage rating is useless garbage nowadays. REally, only the +12V amperage matters. Some 750Ws have far higher +12V amperage than some 850Ws and are thus better than those 850Ws that aren't higher quality in other ways.

alright, recommend me one which would me over recommended? i just dont want it to be more than 200 euro, i would prefer 150, or even 120.

If you're going to overclock the cards as well as the CPU you'll need plenty of juice, as has been said, check the amperage on the +12 volt rail/s rather than the Wattage.
I prefer the 'Victorian steam engine' approach the powersupplies: the bigger the better;), within reason.

im going to sli the superclocked ones btw, but its only like 1058 without boost and normal one 1006.

http://www.inet.se/produkt/6900281/xfx-xxx-edition-750w... wow would that one really be good enough? nice found..!
on my other thead someone recommened me this one though.. http://www.inet.se/produkt/6911364/corsair-hx-750w-80-g... would that be better?


The XFX is more than enough and one of the top quality brands for reliability.

I can't tell if your suggestion is good because that web site isn't working right for me. Can you give a link to the same model from a different site or just post the model number for me to look up?

didnt get so good rating.. but ill copy the specs;
750 W
ATX12V 2.31 och EPS12V 2.92
140 mm cooler
modulärt: yes (?)?
molex; 8
SATA power, 12
6-pin pci express
floppy; 2
name; Corsair HX 750W 80+ Gold Modulär
tried to translate it as good as i could.. does this has something to do with pcie-3? my motherboard supports it and ill use my gtx 680s for it, i guess.

The PSU has nothing to do with PCIe versions. PCIe power connectors are used to supply additional power from what the PCIe slot on the motherboard can supply, usually intended for graphics cards, but they have no impact on the PCIe version that the card is running at.

Those specs don't have the +12V amperage listed. I'll try a Google search on that model number. It probably has enough, but I'l check anyway. I don't see where you listed a price for it, so I'll ask, how expensive is that PSU?

I just looked it up and it seems that that PSU has the same +12V amperage as the XFX model that I recommended, it's just a little more efficient and expensive.

140 euro yeah.. but i want a good one, would it be ok with 750w for sure? otherwise, does this perform better, since its 850w too.. Corsair HX 850W 80+ Gold Modulär

They have the same +12V amperage, so the 850W doesn't actually supply more power. I'd get the XFX model. It is almost exactly as good, but considerably cheaper.

Thanks for your help man. are you sure itll handle 3730k overclocked and 2 overclocked gtx 680?

Please tell me your not playing on a single display at 1080p res with 2 x gtx 680s? Big waste if so. .

im doing it for future proof. +, not even sli gtx 680 can play witcher 2 with ubersampling and only metro like 40-55 FPS maxed out. so it wont be overkill for future games.

Apologize for coming late to the party, but did they fix BF3 problems with hyperthreading? All of the initial performance reviews on Toms/Anand/etc as well as anecdotal info in these forums indicated stuttering or lower frame rates with HT on.

Thanks!

Thanks alot. I'm going for the corsair one just cuz of their reputation then, i dont wanna risk anything. lets hope 750w will be enough then! thanks

XFX has a better rep than Corsair, just so you know.

IDK where you heard that. Every test that I've seen shows Hyper-Threading being beneficial for BF3.

So the i3 like the 2120 will not bottleneck me in games cuz it has 2 cores ?

Oh, the i3 would be a bottle-neck in BF3 MP, but some people might consider it playable. That the i3s has only two Sandy/Ivy Bridge cores at about 3GHz is its downfall in BF3 MP and is why the FX-6100 and beat it with its six cores.
October 4, 2012 11:37:56 PM

i asked many here about the performance of the i3 2120 and the gtx 660 not-ti in bf3 mp and they said it will perform great, so who should i believe now lol

BF3 MP is one of the most CPU intensive games ever. Besides, performance is subjective. I don't consider it grat unless minimum FPS is over 50 and average is at or over 60. The i3 is unlikely to reach anywhere near that in BF3 MP with full load of players.
