No no no...that's 4 GB of ram, because that stupid paperclip will hog 3.8
As far as any early indications I've seen go, Doom3 will be in the 700-800 MHz range too. Yes, more CPU means better playability...but I've never seen the recommended CPU be double the minimum requirement. Even the UT2003 recommendation is 1 GHz...less than 300 MHz above the min.
The only use for OCing in my future, is when the DDR2 stuff is out, the next batch of games is coming out, and all my current hardware is junk. I'll OC it til it bleeds, just to keep it working, at a time when oem POS's will run circle's around it. Then, of course, I'll need the heavy duty cooling again.
Full circle.
