I want to upgrade my video card, but.....

yeah your current cpu is real bottleneck for 6800U, even my old p4 2.53 was bottleneck for it untill I got this p4 3.4ghz . for example I could only play the MOH: pacific assault upto 1024*768 with p4 2.53 but with 3.4 I can play it @ 1600*1200.the dual channel memory technology of new chipsets is also very effective.

if you're going to get that 6800U, you need atleast 3GHZ cpu (amd or intel) to see major boost from your current setup.
