Dual Channel PC4200 vs PC6400

I currently have a Windows Vista 32 bit system with a Core 2 6600 cpu running 4gig of PC4200 ram. I have a Nvidia 9800GT graphics card. The mother board is a DXP061 Running bios v2.5.3

The question is, is it worth upgrading to 4 gig of PC6400 ram? I am a gamer and am hoping to improve performance of the system.

Yes. You don't fully need DDR2-800MHz ram, but you do need faster ram. (might as well buy DDR2-800, its cheap.) I have the 6600, so I know the specs by heart. 266FSB times a CPU multiplier of 9 equals 2.4GHz CPU frequency. Your ram should be AT LEAST twice your FSB, so you need at least 533MHz ram. (266 x 2) I just realized you said PC4200 and not PC3200, so the ram is (4200 / 8) DDR2-533. You don't need faster ram unless you are overclocking. Hows that for a change in mid stream?

lol thanx for the info. I am debating upgrading to a Q6700 cpu would the ram benefit me then?

No, both CPUs run on a 266MHz actual bus. You'd need one of the 8 series chips to move to 333MHz, or DR2-667. You could also try overclocking, you'd need faster ram for that.
