I have the older ASUS P4R800-VM Motherboard and the Integrated ATI Radeon 9100 IGP w/ 128MB memory just isn't cutting it. CoD4 doesn't support the ancient heap of crap so I can't run it (I could if I had a discrete card). I also have a 300W En-Lite PSU (Pk: 340W).
Specs:
Intel Celeron 2.4GHz (Socket478)
Asus P4R800-VM
1GB Corsair Valu-Select RAM (333MHz)
ATI Radeon 9100 IGP 128MB
300W En-Lite Power
