MTL, OC'ing a C2D chip isn't really that hard if you're inexperienced. You just need to do a bit of researching/reading, and if you can find someone that has the same mobo as you to help you with some settings, you'll be there in no time. To push a high OC will take some time and experience though.
Also, yes ALOT of people just get the 6600 and OC it past a 6800. Heck, my 6300 matches a 6800. And yes, a 6800 will probably OC higher than a 6600, but there's 2 problems with that. 1) the higher-rated a CPU, the less proportionate an OC you will get; 2) the price difference between the 6600 and 6800 when you look at the OC'ing potential makes the 6800 cost difference a foolish investment. If you're gonna spend that much money, it will be easily beaten by a $300 CPU in a year or so. So why bother wasting that much money? You can get a MUCH, MUCH cheaper 6600 and OC it past a 6800 no problem. And the difference between a 3.4 ghz 6600 and a 3.7 ghz 6800 in real life performance is not very much.
So, the question is: Are you willing to spend $600 more for a CPU that will finish encoding a DVD or WinZipping a file 30 seconds faster? Is that 30 seconds or less worth $600 to you??? If it is, then you are one RICH dude. If not, then get the 6600 and OC it 😉
Thanks, you do bring up a lot of good points. I also know that overclocking that 6600 though will eat up a lot of its life. I'm still about 3 weeks from building my system, so I'll definitely read up on everything to make sure I have the best parts. Thanks for the help.
