nice, i'm making a almost the same build, 1090t, crosshair iv formula, 5970 though, HDD, ram.. NICE! what is your budget. A good tip, the Crosshair IV Formula mobo has a North Bridge overheating problem, easy fix, you take off the heat sinks, file down the standoffs and put it back on with some Thermal Paste if you didnt know wow highest AA? ddddddddddaaaaaaaaaaaaaammmmmmmmmmmmm!!!!! Who needs highest AA??? I would invest in a better monitor and take down the AA for some performance, you don't need it man but if you want it...
I would actually recommend going for a quad core if you're main purpose is gaming. Most if not all games out now can only make use out of 4 cores, a lot of games don't even use that. And quad cores seem to perform better game wise than hex cores believe it or not. It would save money. You could upgrade to a hex core later down the road.
If you have a 2k budget, go with a bit more ram.
And where's your SSD?! A high price build always needs one for the OS. It makes everything run extremely fast.
And an SSD for a boot drive but id wait for someone to suggest something as im not familiar with SSDs
For now only go with a 955 quad core as they are better for gaming and "bulldozer" processors are right around the corner and these motherboards are guaranteed to support the new octo-core processors in early 2011
so this build is right around 1300$ unless i left something out
