Pretty sure there is no game currently available that uses 8 cores. Ofcourse in the ''future'' 8 cores may be used for games, but currently I am almost certain that even the most performance hungry games(graphics wise) utilize 6 cores let alone 8.
Yeah, I think the best processor really for most everyone out that that games is the Intel i5. The i7 for more demanding tasks, and an i3 if you can't afford the i5. Then maybe an AMD APU for the low, low budget side.
AMD FX processors are really just out of the game, and most every game cannot take advantage of the FX processors. You will also pay $20 more a year in electricity with one of those grossly inefficient and intensely hot AMD FX's.
To answer your question, Zombie615, go with the Intel 4 core. In most games, that is by far the best, and Intel really leads AMD in every aspect. In 2-3 years once games take advantage of more threads, maybe AMD will have a better chip and you can buy that, but for now, get an i5.
