I am at somewhat of a dilemma. I'd really like to get my dirty mitts on a 4870 (or a 260, depending on the prices), but with money being tight and all that, my options are limited to the 512mb version. I have a 24" monitor, will the card struggle with 1920x1200? I've heard that to run 1920 and above you really need 1gb of RAM, just wanted to see if I'd be shooting myself in the foot
