unless I am missing something, everyone keeps saying the 1gb is the way to go but this is in the context of gaming higher than 1900 correct? even looking at the chart for GRID there is not even 1 FPS difference with the 4870 1gb vs 4870 512mb at 1900x1200. It still seems, depending on your viewing limitations, the choice of card can be determined by the gaming resolution. this is, of course, xtremesystems so maybe going overboard is the standard here
