i would actually go the q6600 or similar, you can get them off ebay for a decent price and get them to 3.4ghz without too much effort. the higher multiplier allows better overclocking. q8xxx series overclock like poop. I would not go for this at all as a new build, that would be stupid. Let us know if its a new build, we can recommend you something much better. If just upgrading the cpu, go to ebay.
