The usual move past 2 cores is for apps that use it such as video rendering but not all things use this. I still picked a quad core for my work horse but I am writing apps in Visual Studio so I'll take any advantage I can find.
I would like some opinions to settle a debate I am having with my brother. I have an AMD Phenom II x2, Black edition 3.1ghz, my brother has the Phenom II x4 965 3.4ghz. I am happy with the CPU but he insists that upgrading to a 965 quad core would improve?everything! From all the info. I have read on numerous tech sites the only real advantage to having multiple cores is more efficient multi-tasking. I rarely have more than a game running, web browser and maybe Word at the same time and I switch between these without a problem. Apart from the speed increase is there a really good reason why I should upgrade my CPU? If I see any good reason to upgrade I am more than willing to do it.
