Kudos to ^.
I also hate Intel, with a deep undying passion. Intel (IMHO), has to build in the high cost of their marketing strategy, playing up their own product, which they know would lose out to the vast majority of consumers who are interested (now more than ever, than bang-for buck).
The AMD 9950 Black Edition @ 2.6Ghz is about the best $199.00 for a CPU you could spend, with the superb 9850 Black Edition (@2.5) running a close second at $189.00.
All in all, when running games, it is true that your motherboard, RAM, and more so your video card matter more than the CPU. I just can't justify myself spending something like $500.00 just on a CPU, like in the case of the i7's and the Xtreme Quads Intel has out.
I have built four 9850s in the last year, all for paying customers, and each of them can't believe they only spent around $950 for the whole thing...(incl my fee NO MONITOR, case reused, cd drive reused, no RAID). They got what they wanted, on an equal performace field (game-wise) with any Intel machine around.
If you are price savvy, and it really isn't hard, I agree that for less than $600...you can be in "the big leagues"....
For online Gaming, and for those (like me) who don't need to download streaming video, while playing, while talking on Teamspeak, while playing solitaire, while fragging people on Crysis....AMD Quads..just plain cheaply, stably, reliably, kick butt, and even the little X2 5400+ Brisbane Dual Core, can give ANY Q6600 a run for his money....(with 8gb RAM and a ATI Radeon 4850 at least)!
BTW---for any overclockers out there....you can pick up the AMD 5400+ Brisbane X2 now for 69.99 @ the egg...and it is easily the most stable to 3.3 GHz Dual out there for that kind of money!
save your Intel CPU money for a good video card and RAM, you will thank me later....especially with VISTA.
