Best overclocking CPU?

[Mint_Sauce]

Looking to spec up a top end machine and a big part of that is the CPU! Was wondering what CPU you kind people would recommend for the best performance for money and the best overall performer (price no issue?

What CPU would you get and what mobo/RAM would you mate it with for the best overall performance?

I'm itching to order it up but I've been out the loop for a while so I'm struggling to get up to speed at the moment.

Thanks for any suggestions.

Excellent advice, thanks everyone. I'll go with the Q6600 G0 and the Abit P35 (depending on RAID abilities). Also, I'm looking at 4GB Ram with 64bit Vista, what chips would you go for with the Q6600 G0 and Abit P35?

Thanks again, can't wait to order it up!

Going a bit off topic from the CPU, I saw there's SE16 and RE16 for the HDD, which would be better for RAID?

As per the question, the best overclocking cpu would be the E2140 and E2160 and I'm sure the E2180 will follow in the same route.

Would that be better than the Q6600 in your opinion for performance?
