i agree with richardrds, just grab a decent winchester and overclock away. My CPU is at 2.5GHz right now, so are you really willing to pay like 800% more for 100MHz higher clockspeed? Anyways, I've never read a review of the P4EE that didn't come to the conclusion that they were overpriced and slower than the FX in most apps, especially gaming, and I've read like 5 reviews of it. While the P4 is fast, it's certainly not as fast as its competition, and it is, in fact, often slower than faster P4s, and in games it can be faster than the entire A64 line (although, that's indicative of much of the P4 line). As for the rest of AMD's chips, you'll see they are cheaper than comparable P4s - 3000+ is $155 versus $178, 3200+ is $190 versus $218, etc.
The universal rule I've seen from AMD is that no matter their situation, you will ALWAYS get more for your money by going AMD. When AMD has the performance lead, like with Athlon Tbird and currently, pricing has been on parity or lower than Intel, while giving better performance. Even when AMD was behind with the later Athlon XP, prices were so low that it made up for it and was still a better value to go AMD.
