I have a desktop with an intel p4 2.53 cpu (not my primary pc). The mobo only has PCI and an AGP slot. I've read that a fast gpu with a slow cpu and vice versa is bad. So will this card : Radeon HD 4650 agp 1GB DDR2 run okay on that desktop or should I just get something like a GeForce 6200 AGP 512MB DDR2. Keep in mind I only need a gpu that will run something like TF2 okay, but if that gpu or the cpu is too bad for that, let me know. Thanks in advance.
