So oddly enough I bought a quadro FX500, thought it was a Ti 4200, it was mislabled as such but I think I'm going to keep it anyway. I know its really just an FX5200 but its clock speeds are higher at 270/480 vs 250/400 so there is of course that. It's got 3.6NS ram as well so maybe 550 on the ram if not higher, core im not sure i could make it reach 5200 ultra speeds.
