So, Newegg had this 15% cash back deal the other day (with paypal). I picked up a q9550 2.83ghz core 2 quad, which, with cash back, ran me $270. So now I can either a) sell the q9550 and make $50, or b) sell my e6750 for about $100, bringing the cost of the upgrade to $170 total (plus time/effort). One question is, would I really notice a huge improvement in overall computing experience upgrading to this chip from my e6750? I know that a quad core would improve most video encoding times, however, that is not necessarily enough to make me want to spend this much on a cpu. :\ One thing I was interested in is the Xfire broadcast feature (don't know if anyone is familiar with it). Basically it encodes in-game video as you record it, and uploads it, so others can watch it live. It causes a huge hit on fps, and I'm wondering if, with a quad core, I would get much better results (would the video encode on 2 cores say, while the game is using the other 2). Overall my system plays the most recent games fairly well, however, I sort of expected the 4870 to handle Fallout 3 and GTA 4 better, and can't help wondering if my CPU is the bottleneck (even clocked at 3.2ghz). Anyhow, does anyone have experience with this chip, and can share their experience?
