I am using imac 27 duo core, i found out that if i run Fusion and macintosh together, my ram is not enough to do it, it end up become slower, coz i like to open lots of programs at the same time. Do u think i should get more ram or get a ssd and install Window and macintosh in it. Which one is faster, in term of running lots of programs together. I personally prefer to change ram, coz it is so difficult to change the hard dice in imac. And it is cheaper for ram. It will be extremely helpful if u can tell me where to get the cheapest ram and ssd (<40GB). thx a lot
