[citation][nom]atdhe[/nom]Yeah but even that won't make that much of a difference, just a couple of percent. My point is, if you want to buy a 6 core CPU, wait 2-3 years before most major tools become cleverly multi-threaded. Buying one today just is a waste of money because at that time, there will be a better 6 core cpu, and until then, a quad-core is all that you need.[/citation]
It makes a huge difference, actually. Rendering and encoding on a 6 core is up to 50% faster in many cases than on an otherwise identical (clocks, architecture, etc) quad.
