I wouldn't go with Intel, personally. If you want a much faster processor, go with AMD. They have a 2.8GHz six core processor for $199.99 on Newegg and a 3.2GHz six core processor for $295.99 on Newegg.
Also, according to newegg, they use fewer watts than the Intel i7 processors, too, even the one you said you were getting. However, if you are getting an AMD processor, it is likely you will have to find a different motherboard if the motherboard you have in mind is not compatible with AMD processors.
How does that even...
The AMD has an equal clock speed of some of those, and more cores... so... how... that doesn't even... *brain explodes*
:/i loled...
Intel has much better performance, however, you are correct if you ment to say that AMD cpus have the best bang for your buck, but if you want the top dog machine, you would want to go with intel
thats like saying, " my pentium 4 is clocked faster than that pos quad core at 3.4ghz, so my pentium 4 is faster right? " < a bit extreme and rediculous, but im just prooving a point.
Intels i7 920 quad core processor is faster than AMDs fastest six core processor.. i dont really know why, but thats just the way it works.
