Being the dutiful friend, I'm upgrading my buddy's P2-450 Dell desktop. He's an architect, and back when he bought the system he got it with the NVIDIA RIVA TNT 2 16MB graphics card, which was the sh*t at the time. I've already maxed out the memory at 384MB. Can anyone please help me decide which current graphics card I should upgrade to? I'm concerned about spending too much on an overpowered card, considering the limitations of the system (P2 architecture, 100MHz FSB, 2X AGP (if that)). Is spending $100 on a GeForce 3 Ti 200 complete overkill? Thanks in advance! - Matt
