Thanks Browz, I have an external Iomega Predator on USB 2.0 anyway. Alright, thanks and I'll get the NEC. How is it for the buck? I've seen insane overclocks on the Celeron Ds. My friends urn a 320 on 478 which runs at 2.4 GHz. His has hit 3.7 GHz with no issues. My 520 is like running so nicely on a Duramax and fully stable at 3.4 GHz. So, I should be able to hit 3.7, right?
