Well, my P5K-E arrived today. After a few hours of head-scratching regarding the LAN (Not being detected, had to use dad's comp to update router's allowed MAC addresses). I've not run any benchies yet, but already, i can feel this board has something about it. WITHOUT any extra vcore, i managed 3.5Ghz without a problem. Got some Dominater memory running, simply because i like Corsair

.
Gonna try giving it 1.4v later, see if i can hit 3.8 or even 4.0. 4.0 has been a challenge for me for a long time. 3.0 was what i always wanted to hit, but when it's already that at stock, it's not so amazing

.
UPDATE: Very simple; 1.5V, 444Mhz FSB, startup, bam! 219K AM3 Score and 11.734S SuperPi to 1m. Yet to run 3DMarks so will report back soon. CPU-Z:
CPU-Z Validator 2.1. 54C Core #0 and #1 Temps though, perhaps i've got one with a "stuck" temp sensor? It's only reported at this temp in CoreTemp, whereas RealTemp 2.41 reports it as 44-46.
