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?
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.

http://www.inet.se/produkt/6909557/corsair-ax-750w-80-g... would that one work?

What do you think of this one? XFX is among the top brands (they use Seasonic to manufacture their PSUs) and this model should both have a good rating of power and a good price at under 95 Euros.

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 ModulärThey 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.

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

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.
