I've upgraded my main system about as far as i can go and am looking into buying a new one. I've been building pc's long enough to know the game on most everything but reading up on processor developement has got me a bit stumped. Basicaly- Dual and Quad cores are not being fully utilized yet, but are predicted to be the way of the future, especialy now with 64 bit integration. But I have also read that the multiple cores' are only important for multi tasking, and if you are just looking for performance just focus on speed. Now is this the case because applications aren't utilizing the multiple cores yet, and if i buy a 3-4ghz processor will it be trumped when the dual and quad cores start being fully used. Guess i dont want to be where i was when i bought my last pc and everyone said the pci express was dead tech and i should get a agp mobo. Is this the time to wait and see how thigns turnout first? or a good time to buy?
