Depends what games you want to play and what your budget is. Like are you going to try and get 60fps out of Crysis 2 and Metro 2033 or just out of COD or some less demanding games? As far as monitors I prefer the 16x10 aspect ration of the 1680x1050 screens for gaming vs the full 16x9 widescreens, and that resolution would be less demanding on GPUs and save you some money on the screens as well. Asus is a good brand, EVGA would be my recomendation for warranty support, alot of there cards have lifetime warranties. There is an EVGA gtx 460 on newegg for 145 after rebates with a lifetime warranty that is a very good value and will max out most games at 1680x1050, but some newer DX11 games will struggle at max settings. There's also an XFX 6850 for the same price that would also have a lifetime warranty. Similar performance to the 460 although my personal preference would be the 460. Those 2 cards are probably the best bang for your buck with a good warranty right now, but you won't be able to max out the newest games with them. For that you have to go really high end and spend alot of money.
