Picking up thread from earlier this year re: i5-750 versus Q9650. I have a Gigabyte LGA775 board which currently has an E8400. My primary application is for DAW use... Cubase 4. My cost-containment upgrade options are to pop in the fastest supported quad (supports up to QX-9650 and I think QX-9770 as well) or bite the bullet and get new board/cpu with i5-750. Yes I know the i7-xxx are the bad boys, but again, this is cost issue. The bottom line question: is there a *significant* (not just a wee bit) performance difference between these two? If so, what makes the i5 a better quad? I get overwhelmed with charts and benchmark data trying to research this. For example, I note the 12mb of L2 cache on the Q9650 versus 8mb on the i5-750. This is confusing in terms of performance difference, when the forum talk generally says i5 is better. Thanks for any help on this.
