While on the topic, I'm basically having the same problem with bad performance. It works okay on very low graphics settings. Will the ATI Radeon X800 All In Wonder card solve my problem? It's 256 mb ram.

My computer has 512 mb ram, 3200+ AMD athlon 64 processor (2.20 Ghz), and I am using the stock video card which is a ATI Radeon xpress 200

Specs for the ATI Radeon X800 All In Wonder are here:
Installed Video Memory 256 MB
Memory Technology GDDR3 ****M
Resolution 2048 x 1536
Color Depth at Maximum Resolution 24 Bit
Max Monitors Supported 2
Video Chipset ATI Radeon X800 XL
Video Compression Standards MPEG-2
Video Standards S-Video, Composite video

Thanks for any help.
