^yep. I think 1920x1080's definitely the way to go. You won't be able to max BF3 or anything, but IMO it's better to have a big, pretty screen and lower settings on than a tiny screen and all the eye candy enabled. I recommend a 23-incher, though. At that point the pixels still aren't big and annoying, but you can get much more into your games. Here we are: http://www.newegg.com/Product/Product.aspx?Item=N82E16824262012
I've got a 1gb 460 (comparable to the 6850
) and a 24-incher, and even games like Crysis 2 stay above 60fps and look great on middling settings.
