You'll need a quality 650+W PSU. The GTX 590 is really bad value for money though, I suggest you go with a 560 (Ti) SLI setup.

Id be looking closer to a 700-750w PSU with a GTX 590.

Look for recommended brands and a good 80PLUS rating. Corsair, Antec, XFX and SeaSonic are all worth considering. Modular would be recommended too.

Not only is the gtx 590 a bad value, so is the 980x. The i7 2500k/2600k best it for a fraction of the price.

the i5 2500k for gaming. i7 2600k is totally unecessary. If you want to throw away $100, ill take it. i5 2500k is 97% the chip the 2600k is, at 65% of the cost. a 6-core processor does nothing for you for gaming, at all. so the 9xx series i7's are not a valuable buy.

GTX580 in SLI is the way to go, and i would suggest an HX1050 for that setup. Enough juice, and a good price. If you want a great psu, the AX1200 is the way to go.

Do not buy 560ti in SLI, you will hate the micro-stuttering.

also, your RAM, buy an 8Gb set, but get 2 sticks of 4Gb, not 4 sticks of 2Gb. One is, with a decent aftermarket HSF, you may not have all your ram slots available, so you will need to consolidate it.

The article that tom's did on micro stuttering showed that anything above a 6870 should alleviate the issue. I don't think the 560ti would be an issue.

Although, I think its better to start with one more powerful card. Then when the time comes that you are bogging the system down, add a second card in there.

If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs.

Go with the 2600K over the 980 - 1366 is very outdated, especially with the pending release of LGA 2011. That $300 CPU will easily outperform the more expensive $900 one you want to use.

And yeah for the price that a single 590 is going for, I'd definitely second the recommendation of using dual 580s instead.

Also if you're paying that much for a system, invest in a good, solid SSD and pair that with a 2TB hard drive instead of going for a RAID configuration with 2 1TB hard drives - that is worth it in the long run.

As far as PSUs go, I'd look into PC Power & Cooling, Corsair, and Seasonic are all excellent brands. Avoid anything that's a barebones, no name PSU and make sure the one you're using is certified and rated at least 80+ bronze or better. Silver and Gold rated PSUs are way better but they'll run you quite a bit more.
