Obviously the Athlon 64 4000+ is a little powerhouse. It's not for everyone though, the biggest problem right now is its pricing, which is in the 500-600 EUR/ USD range. That's a lot of money people. If you want the best though well, then nothing much can match this, except the even more expensive FX-55 CPU of course. Now I already stated this in the beginning, we are a hardware site with a strong focus on gamers. So if you ask me what a gamer should buy, at this time and moment it still is an AMD CPU. There's not one consumer Pentium 4 CPU out there that can match the game performance of this AMD CPU. If you are not so much a gamer and more a desktop/office user, you might miss HyperThreading. So as you can see it's not exact math here, both giants have slight advantages and disadvantages. But for a gamer the AMD CPU's still offer more bang for your bucks.
