That will be a nice upgrade. I remember when I went Intel (2500k) after my AMD 965 black. That was the largest difference in performance next to ditching spinner drives for SSD's I've experienced. I'd run before/after bench if I were you, because the difference is going to be massive.
Is this common for some WU's? I was hoping it would kick up to 100% GPU load at some point over the past couple of days, but it just hasn't. Using v7 currently. I tried uninstalling and it trying GPU tracker (worked on my rig at work), no dice. Just reinstalled v7 and same crap, only utilizes 68 - 70% GPU power. Any ideas?
Sorry for the late response, had to celebrate another Royals victory. Hardware is 2600k/4.4ghz/1.34 volts on an Asus p8p67 pro with a 5850 video card. It isn't going to produce big numbers, but every little bit helps. That stupid screen shot did not turn out, sorry. I'll post again from work tomorrow, but the log kept throwing errors saying something about "unable to read stream".
If you overclock that pentium to the 9's you'll be fine until you can afford an i5. It's hard to say if you'll take a performance hit in the mean time or not since it will really depend on how well the pentium you get will clock. If you aren't going to overclock then forget it and hold out for i5 money.
