best quad for overclocking?

[toon_mad]

hi all, the final piece of my pc upgrade is the cpu, ive got the new tower (nzxt guardian) from another shop and am waiting for these from overclockers:

foxconn blackops x48 motherboard
g-skill 1600mhz 2x2gb ddr3
ati hd 5850

so the cpu should be 775 socket and can perform well with the above, i was thinking of the q9550 but dont know which is the best stepping (E0 i think), also how will i know im getting the best vid chip, the less volts i run through it the better, im running on a true120 push/pull and have had no problems temps wise with my q6600 @ 3.76ghz, though a lot of volts were needed - temps never exceed 58c.

also how much heat can these q9550's take? i was hoping to get around 4ghz or higher if possible

Cheers

E0 is the stepping you want, the one's I tested started to play up with around 65c when pushing high FSB. Hope you got good money for that Q6600.

C0 and E0, you'd be dam unlucky to buy retail Q9550 C0 this far down the line, however they are still around...

Couple of people have tried ringing ocuk in the past about the stepping, but they have both versions in stock apparantly. might be worth ringing to see if they have any further info, but i wouldnt hold my breah.
