allright, so here's the deal: I've got a choice between: some intel core 2 duos and pentium dual cores (E6600 and so on, between 2.2 and 2.8 Ghz) an AMD Athlon II X2 220 (2.8Ghz), an AMD X4 630 (2.8Ghz) the new(er) Intel i3 530 at 2.93 Ghz. I'm going to use it for heavy office work, a game from time to time and a lot of converting and internet. I've got 3GB of RAM, might get another gigabyte extra if needed. I've got a lot of programs running side by side. So what do you guys think, which will suit me best?
