If you got a lot of money to blow away, and you're a gamer then get the Athlon64 FX53, if you don't need the best of the best, willing to pay half and get 95% of the performance, then then Athlon64 3400+ is the best chip. Intel isn't ideal for gaming compare to the Athlon64 chips.
Agree with scottchen. If gaming is the only consideration, and you're actually willing to fork out for an EE chip, then an Athlon FX is the way to go.
Or if you have to stick to intel, you could probably actually get higher performance with a P4 2.8 overclocked to 3.2-3.4Ghz & paired with some fast RAM, than with the 3.2EE. and it would cost a whole lot less.
If you`r in to gaming, AMD is the way to go, beside, that P4 is hot as hell !
You dont want such a overheating thing in your system, AMD has cool and quit, you can let the cooler fall out when your surfing ore watching a movie.
And beside, in a few months Windows XP 64 bit comes out, that will give you extra performence in gaming, AMD is ready for it, Intel not.
AMD is the way to go, unles you`r a die hard intel fanboi, go intel !
