for normal every day stuff, no, for gaming, possibly.

I have a dual core, and its a little slow sometimes cause i have 6 harddrives so it will lag trying to access back and forth cause ill be playing music off one and using the others for media or something.

the quad core is prob more for graphics intense stuff, like HDMI Gaming (crysis comes to mind) and stuff.

I play 1080P blurays on my computer with no problem with a ATI HDMI Video card that cost like $100
