Bluntness? Ha! Its okay, we're family.
It is a $300 waste of your money, Leon. Especially since you are only running GTX 480.
But as i said when i upgraded to i7-920, "i upgraded so our readers don't have to"
Well for the longest while, I've wanted to be able to run SLI and CrossFire on the same platform. I got a P67 board so now is my chance.
And it wouldn't be a $300 waste, if anything it would be $100 since the very least I'd buy is the i5-2500K.
I'm getting a bit more into working with videos. I'm encoding a whole lot more these days and having 8 threads would help speed that up. Not to mention ABT's DC like Folding@Home and such. Next is the fact that just like you said, I'd be upgrading so the readers don't have to.
Really wanted to discuss the potential advantages versus the disadvantages of either choice.
