is there such thing as a 8 core computer?
The evga SR-3 socket 2011.
8 cores right now is fairly useless, as very few applications actually make use of 4 cores let alone 8.
Sure, the Bulldozer architecture has an eight core, AMD FX-8150. It's not that good. An i7 with hyperthreading enabled tends to beat the Bulldozer architecture in performance.
