Need help picking the best CPU for my setup?

[bushwickbill]

Hi all.
I am currently looking for the best idea for the most gaming performance I can get.

I just won two 1GB sticks of Corsair DDR3 1333Mhz Ram but my MOBO does not support it.

So I think I will sell the DRR3 Ram along with my C2D E6400 and XEON 3070 to try and buy the Best CPU i can get.
So am I better off going with a C2D 8600 or E8400 instead of a Q6600 or Q6700?

A quad would future proof my Rig a bit more than a C2D wouldn't it? Or should I just go with a really fast C2D

Please keep in mind that I am running four 1GB sticks of G-Skill DDR2 800Mhz Ram so I can't run my FSB too high right?

I am not too up to date on all the newest Intel CPU's or which ones give the Best gaming performance.

I do have a Zalman CNPS 9500 to fit onto whichever CPU I get.

So can someone please tell me what CPU will give what kind of performance over the other?

I do know that a fast C2D will be better in games right now over a slower Quad, But can't
you Overclock a Q6600 or Q6700 into the 3.5Ghz area?

I know as the games become more CPU demanding, Having four Cores will help out more then.

But how much more? Thanx for any and all help.

I am not totally stuck on the getting a new CPU. But how well can a XEON 3070 Overclock compared to what I can sell it for along with my E6400 and buy a new one?

What motherboard do you have? It may not even support the new CPUs.

Just go with the E8400. As long as you keep to a 1:1 ratio, the max OC you should be able to get with little work is a 3.6Ghz OC.

I have a ASUS P5B vanilla.

ASUS P5B supports 45nm CPU's. The E8500 is a Great sub $200. CPU at the moment. A Zalman 9500 should keep it nice and cool up to 3.33 or so!
