i currently have an e6600 running at 2.9 ghz without breaking a sweat. the new c2d are beautiful.. great processors that intel honestly lowered the clock rate on for some odd reason. you oc them like crazy.. i can run my computer at 3.1 with ease. on stock air. orthos stabl for 20 minutes... not much time but whatever.. they oc like crazy... i have the gigabyte GA-965P-S3.. its a beauty for low cost ocing
the d series are great processors.. they just run at unBELIEVEable high temps when u get to high frequencies.. if your are buying.. go with the e series... cant beat it.. amd wont have an answer for 4-6 months..
yeah.. if you have the money.. get the e6600, or better.. if you can go for the quad cores,, that stuff is nutts and will hold up in time. there really arnt any programs to take advantage of them. i just built the new system with the e6600 and its awesome.. has great ocing.. but the e6300 is great as well.. with no time, and a great mobo of course, you can have the e6300 running at the quad speeds.. go with the new intels for now.. amd has nothing comparable at the moment..
