Hell, a GF4MX440, Radeon 7200/7500 class graphics card would probably suffice for your CPU, perhaps even a GF2MX400. I currently have a V3 in my Celly 850 system and its a pretty good match even. Of course, with a GF3Ti or Radeon 8500LE, you could bring it over to your future system, assuming the future is near 🙂
