From what I've read, GCC is only able to make minimal use of multiple cores as the bottleneck is IO bandwidth. It might end up being the case that a faster CPU will outperform a slower, multicore CPU, but this is just a guess.
I'm honestly surprised that compiling with GCC and watching a movie would cause the system to be a little unresponsive on a dual core - movies aren't generally that power-hungry (unless you're talking about HD). Even then, the responsiveness issue can be fixed with lowering GCC's task priority. Also keep in mind that the fact that a quad core is nice and responsive indicates that it's not being fully utilized.
Ja, you make a good point. Which begs the question of whether that extra cash would be better spent on a nice, fast RAID setup, to increase IO performance.
