^is ocz a good brand of psu? 660 is better than 7770
I would get a Windows 7 OEM 64bit.
I would also dump the 560. I had a couple. they sucked and were very hot.
the 2 suggestions of the 660 non ti and the 7770 would probably be fine for your resolution. I'd go for the 660 personally.
the rest would be okay but maybe stuff I wouldn't normally buy for myself. but that's okay.
add: silverstone PS's are good.
OCZ is one of the trusted brands, as is Seasonic, Silverstone, and Corsair. The 7770 Ghz Edition is a very capable overclocker as a video card and thats why I suggested it.
Sure the GTX 660 is better, but so is the GTX 690, and there are reasons why I chose the parts I did, money constraints.
I agree with Thomas's build. The 560, 7850, 660, ect. are better of course than the 7770, but look at the monitor resolution of OP. A 7770 would be perfect fit for that and save money to make a more well rounded, quality build.
