So the laptop I'm getting has a mobility radeon 7500, which I hear is a pretty good chip for games, but it only has 16 megs of video memory. Will this screw me over? I mean, if I wanted to play WC3 or UT2003 on this laptop (has a 1.8 P4 w/ 256 DDR ram), is it going to run chunk-style due to a lack of Vram? It seems kind of stupid to make a video card for laptops that's all fast and whatnot, well suited for games, and then embarass it with so little memory. Whats the deal?
