I have a really old IBM x20 laptop (~500-600mhz, 10gb hdd, 64mb ram, win98), do you guys know where i can find out what kinda video card I can update this thing with?

i only do normal web browsing and programming on it so cpu speed is not a problem but i can't really stand 800x600 on such a small screen, but do guys thing that the resolution is limited by the screen itself or the video card?

thanks
