Way..way...way..overkill right now. It will be 12 to 18 months before any games will need anything close to that kind of horsepower.
You could save yourself some money buy going with a dual or quad chip.
As far as your question goes, have you looked at Dell's Outlet store?? They have open box specials, you probably could find a good monitor there. Not sure why you need 2ms response time. I have a Dell 24" LCD monitor that is 5 years old, and still going strong. I play a lot of FPS, and have never noticed any ghosting, or anything bad with the monitor.
right now there arnt any great i7 coolers btw dont listen to the other guy if you have the money for i7 now get it and save yourself the pain of the upgrade later. there no point of buying old tech if u can afford new tech. i would also reccomend you get a 20-22 inch monitor for that vid card.
Another thing is psu. 650w is small for a $2k system. Get a beefier one. It's a pain to change out later. With x58 able to run both cf and sli, you want to keep dual/quad gpu upgrading options open by using a psu that can keep up.
For the heat sink, I'd go with the "Thermalright Ultra-120 eXtreme 1366 RT" if you want to stick with air cooling. They should be releasing soon. The heat sink is out now, but the combo with the retention bracket for 1366, and the fan mount is not yet available to my knowledge.
yeah, but i could get 2 4850s for around 280, and they would both be oced already, i think it would cost around 380, and if i ever did crossfire 2 4850x2s then im sure i would have to get a bigger psu than 750
