Not much difference - hardly noticable in "real" use. Download and run CPU-Z then post the CPU screen, mainboard screen, memory and SPD screens. Your CPU is quite good at overclocking to 3.2GHz (without OCing DDR2-800 speed RAM).
IF YOU HAVE PC2-6400 (400MHz) RAM then run the multiplier at x8, BUS at 400 yields core speed of 3.2GHz - keeps clocks nice (FSB-DRAM divider = 1:1) and makes the RAM very happy.
