jhones99 :
will future application developers add multi - processor support to applications
should a buy a slow quad core or fast dual core
i used laptop mostly for running virtual machines like vmware, and some processor intensive applications
As another person said, a quad core cpu will be much better, as it gives both the primary os and the virtual os a lot of breathing room.
Now are those processor intensive applications multi threaded for 4 cores or even 8 threads? if so the core i7 720 will be really good choice.
If not, it can only use 2 cores then the core i5's/ dual core i7 would be a better choice as there higher GHz.
My last question will be, are you wanting long battery life? If so then you'll want to chose a dual...
