from Pc3200 to Pc4000. Worth it?

I am thinking about memory upgrade. My bios have 5% to 30% overcolocked, I did overclocked 5% then it crash in gaming. I am using 4X512MB (3-3-3-8) DDR PC3200/DDR-400 running in 200Mhz, which I cant overclocked. Will DDR PC4000/DDR-500 improve CPU speed and FPS much better? If yes then, which one you would buy it. If no, then let me know to not bother upgrade memory.

If you find more memory that un in DDR PC4000/DDR-500 will work on ASUS P4P800SE in intel 865PE chipset, lets me know.

I would say no, because I don't think it would improve that much if at, all plus you could save the money for a new setup with ddr2.

Alright, thanks.
