Future planning.. $2000(cdn)

in the future I want to build a dual-cpu computer, just for the fun of having it (im a heavy multi tasker, runnnig at least 10 apps at a time, sometimes more then 20, including multiple games)

I was just curious as to how good of a dual-cpu computer I could get for $2000 now (i wont be buying until about august, but i want to speculate now, to see how much money i would need for the standard computer then)

Honestly speculation on a system build is of little use. In 3 months there will be a host of new products and price changes that will make the market very different.
