The Q6600 does not hit 3.0 99% of the time without a good aftermarket cooler and a voltage increase. Taking into account all of the stress you put on your MB doing it as well shortening its life and greatly increasing the chances of burning your system up its just not worth it in any way. If you are a gamer and dont feel like risking a new MB or CPU in possibly hours after first boot then stay away from the Q6600. If you dont game then there is little to no point in OCing the Q6600.
I dare to see a Q6600 system bench as good as my x2 6400 on a new 790fx MB. On top of that most of the venders are saying they wont be supporting the new Intels coming out on the current chipsets. So when it comes to upgrades AMD is the only clear path atm. In a little while the new AM2+ chips will be out. Unless you plan on dumping over 700++ on an Intel now you might as well just wait and enjoy your Spider rig with a good X2.
I like how you did that. Commenting on a processor you don't owns OCing performance. I happen to know for a FACT that most G0 Q6600s that I've seen and worked with will do 3.0 GHz without going over the VID of the processor. You don't stress the motherboard by moving to a 333 MHz FSB unless you have a really old one that doesn't even support 333 MHz FSB. You don't have a clue of what you speak. Most $20 aftermarket coolers will accomplish this. I know a guy who uses an Arctic Freezer Pro 7 and gets 3.6 GHz out of his Q6600.
Also where did the $700 figure come from? The processor is about $300 max, and if you wanted to go high end it'd be a motherboard for about $240. That's about $540 and considering everything else is the same. Video card, Memory, all that stuff would be the same. A good air cooler is maybe $60 max, so I'll give you $600.
As far as benchmarks, if I felt like shelling out the money for a decent graphics card I'd run some 3Dmark06 against you. However I don't care about a great graphics card as this is a F@H machine for me right now. Perhaps we can go toe to toe once the HD3870X2s come out and I get 2 of them in an X38. Other than that let's go for some synthetics! $20 I win almost everything but memory bandwidth and latency. I don't personally know the potential of a 6400+ but from every benchmark I've seen I have no reason to think it would beat a 3.6 GHz Q6600.. Unless of course you mean 3DMark06, in which case we all know that GPUs are where its at for high scores there.. and guess what? They cost the same for an Intel system as an AMD system!
If you are a gamer and dont feel like risking a new MB or CPU in possibly hours after first boot then stay away from the Q6600. If you dont game then there is little to no point in OCing the Q6600.
Also that has to be the quote of the year. I'm going to burn up my motherboard possibly in hours after the first boot? So if I don't game, there is no reason to OC the Q6600, but if I game I will burn up my motherboard by OCing it. But if I game I'm better off with a 6400+.. I just can't even make sense of this, it's hilarious. For the record there are other things to run on a Q6600, like F@H SMP.
