It's practically *made* for 2 and 4 cores. Single core enhancements were added later. Volker's recommendations is based on his own tests with the patches. I'm on a dual core Intel E6600 and the patches help a big deal to keep the GUI responsive and fluid. Also note that there's much hate and fanboy-ism around this issue. Expect people telling you how this is crap, or how the default Linux scheduler is crap, etc, without them really having a clue what they're talking about. (I am *not* referring to Volker here, mind you.)
