Bought Quake 4 recently and really enjoying playing games again. Currently it's only on lowest settings with my FX5200 64MB. Would love to multiplayer it on high I'd like to upgrade the card but confused on what to get with some 128mb cards being more expensive than the 256 etc... I want to play that Elder Scrolls IV: Oblivion but understand it's very hungry... Card has to be AGP, as there's no PCI express on my motherboard. Rest of setup is AMD 3000+ clawhammer and 1.5 gig RAM. Any suggestions much appreciated.
