Kitire said:What? Dude.. AMD opteron has DUAL cores, so therefore 1.8x2=2.6GHz, that is better than the 4000 stock, and cheaper i believe. But if you decide to OC, you will get it much, much higher than overclocking a 4000.
Correct me if i am wrong.
Correcting you because you're wrong. First of all, 1.8 x 2 = 3.6, not 2.6. Second, if its a contest between those two, I'd personally go with the 4000+. The quote, "You can overclock Dual Cores to Single Core speeds" won't hold true in this case. The Opteron 165 won't get anywhere near 2.8GHz while the 4000+ will likely reach 3.0GHz.
And the analogy isn't right. You don't just double the clockspeed on a Dual Core. If you're running a game on a Dual Core processor, it will only run on one core. That means that on a stock Opteron 165, the game will run at 1.8GHz, MAX. Now, if you were to run a second game (or a really intensive program) while you were playing the game, then the second program would run on the second 1.8GHz Core. In the Single Core, both processes would be running on the same 2.4GHz. That still doesn't help you too much in gaming though. Theres no way processor will take up .6Ghz of the 2.4Ghz that the processor has, it just won't happen.
Until games utilizing both cores at the same time come out (6-8months, or more) Single Cores will still be the best choice for gaming. Even then, you can't Double the clockspeed. Sure, an Athlon 64 X2 4400+ might beat a FX-57, but not by a difference of 2.8Ghz to 4.4Ghz.
I'm a Single Core mascot No Dual Core for me, atleast not yet.
