There's a lot to be said for 'cherry picked' engineering samples

I set out to hit 4Ghz with a low multiplier. I've hit that and am stable, Crysis plays nice (1920x1200 4xAA High Config '35fps) and performance is what I want it to be.

I'm also on air so have really gone as far as i can, temps are high 60's under Prime95 load and 37-40 on idle

Would've gone SLI 9800GX2's but am waiting for the next batch of GX20's before I do that, hopefully it'll be soon so I can use the EVGA step-up program
