don't know... I just added a ATI 9600 myself to replace the org Nvidia 5200 and everything has improve greatly since.. Vue has yet to crash since I installed it... I did download and install latest drivers but I also have had a redeon 7000 (pci, hacked PC card) and I think some of my problems was having to diff manufacture cards on one machine. though the only thing it bothered was Unreal Tournament and Vue.... both are running 100% now.
