The 2500k is better because there aren't many programs that can make use of 8 cores. You're pitting 4 very fast cores against 8 slower cores. The 2500k wins by a beefy margin in gaming and apps that don't use more than 4 threads.
I'd read a few reviews and look at a few benchmarks. http://www.anandtech.com/bench/Product/2... the Core i5-3570k and the Core i7-3770k are coming out next week. These processors are a little bit faster than Intel's Sandy Bridge processors.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
