Im about to buy a 4870 and a new monitor, but im not sure if i should get a 24'(1920x1200) or a 22'(1680x1050).If I get the 24' I definately wont put on any AA,but if i get the 22' I might put on like 2X AA if its necessary.Can the 4870 handle 1920x1200?
More aboutwhich resolution 4870
Don't be ridiculous, if you can afford the 24" buy it. That card will run it with zero problems.
The only game you wont be able to run on high settings is Crysis with 2X AA. Otherwise I wouldn't worry about the slightest thing.
