just a quick question....if i am using a 6600gt ddr3 video card...would my cpu be the bottleneck to the card (i.e. because of the cpu so that the 6600gt cannot perform it true power...i hope you know what i mean )
Yes and no... I mean, I was able to play Need For Speed Most wanted on a PIII 733MHz and my Radeon 8500. It actually ran quite well.
Game performace is more based upon your GPU than your CPU. Not to say a good CPU doesn't help; I'm sure you'd see quite an improvment over your old MX400.
