I am thinking about getting a new computer and, since it has been a while, I am out of the loop on computer stuff. When I got my last one the dual processors were coming out but not a lot of programs supported them so I skipped it. Now everything is quad core multiprocessors etc and I am kind of clueless. What is the difference between dual core and quad core .. I know one is faster but I honestly don't see too much speed difference on my work machine most of the time. What is all of this stuff though? Thanks
