I already owned a E8400 that ran 3.6GHz (400*9) at 1.225v. I gave it to my brother for his build. Now I'm hesitating... I already have some hardware : HD4850, 2x2GB 1066MHz, etc. Correct me if I'm wrong but in high resolutions the GPU is more important than the CPU. So a Q6600 at 3Ghz (a small OC 333*9) is more or less (by like 3-4fps) equal to a E8400 right? So a good OC'd Quad Core is not a bad option for Gaming. I also heard Quad Cores are also great when it comes to confort, like multitasking. Are the newer 45nm Quads worth it? They have less cache (6MB) and the multiplier is lower too but they have a lower power draw and heat dissipation (Q9300, Q9400 for example). I plan to overclock my CPU, so : - With the Q6600, I could get without much trouble 3Ghz (333*9). - With a Q9400, I could get without much trouble 3.2GHz (400*8). Q6600 (3.00GHz) VS Q9400 (3.2Ghz) I can't decide... I would love to get the Q9550 for the 12Mb of cache, but it's too expensive for me.
