Lol do not buy a AMD CPU ..
AMD say that if you have a 2.3ghz Quad core and you are trying to play a game that needs 3ghz it will get ??something?? from the RAM and GFX card What a load of rubbish,.. i have a 2.3 Quad core but still he thinks that it will use the RAM instead of the other 3 cores (they say it doesnt use all the cores at once lol WTF ... go for INTEL they are alot better faster and they say that it uses all four cores.... AMD do not know what they are talking about i was on the phone for about 130mins still the guy was sure and many others lol .... Please Look and read up about the cpu (BUY INTEL NOT AMD) ive even got a couple of softwares showing all four cores working at once lol.

lol o and yh i got a phenom 9600 2.3 at $300 but if you go INTEL you can save alot of cash to RATING

yeah, dont listen to them. It will work perfectly. That rating is for Single core Pentium 4s. As long as you have multi core, or a fast Single core Athlon, you will have no problem. The brand of cpu has no effect if the game uses all 4 cores or not. If it supports multi-threading, the Phenom will work just as good as the Q6600.
