CPU time doesn't mean jack... all that crap in the other post about CPU time means nothing, a quad multitasking is snappier.
What you meant to say was, it doesn't mean jack to someone who regards "hard facts" and "reproducable results" as a logical argument. The people who don't believe in all this 'science' crap are usually the ones who much prefer things that can't be quantified, qualified, tested or proven -- like "snappy" and "it feels better" and those sorts of things.
The only reason I said that is to keep from arguing the point, I provided more evidence than needed proving what I was saying....
And by evidence, you mean blatently incorrect assertions about game engines and your feelings about your PC and it's "snappiness" and your want to push all our opinions on everyone else because you've had a few quads -- scientifically reproducable and measurable results be damned.
The answer goes like this:
Dual core for gaming and pretty much any "normal" amount of multitasking anyone will do like IM + WMP + game + Skype + AV + other misc stuff like that.
Quad core for video/audio compressing, professional Adobe apps, and ridiculous things like playing two games at once
Duals overclock better, cost less, apply less stress to the motherboard, use less power and put out less heat than a quad. Which means, unless you NEED the quad, then it makes far more sense to buy the dual.
