Legion Hardware examines the effect of processor power on graphics.  The 8800 can currently handle anything thrown at with ease, but if the processor can’t keep up then you won’t get the performance you expect.  They test  a series of AMD Athlon64 X2s, the 3800+ ,  4200+, 4600+ and the 5000+ and also Intel Core 2 Duos, the E6300, E6400, E6600, E6700 and the X6800.  Find out what effect a slower processor will have on your dream graphics card.
“Although the GeForce 8800 GTX is best suited to high-end systems, it can be utilized quite well on slightly slower processors. Of course we are not talking about slow processors here, in fact quite the opposite. However, the 1600×1200 resolution showed almost no performance variations between the eleven configurations with the FSAA and Aniso settings enabled. The only game to show noticeable performance differences when using lower clocked or lower performance processors was X3: Reunion.”
