Hi!!

I'd like to make a HCPC but I don't know which CPU I should buy to easily run HD videos (like Bluray discs).
I'm looking at Intel products with integrated GPU, but I don't know how many power I need.
Sandy bridge, Ivy Bridge, even better?
Dual Core, Quad Core?
2.30GHz, 2.90GHz, 3.40Hz?
I'm not searching for the most powerful but simply for the quietest though powerful enough to play any video without any quality drops.

Thanks!
