I am wondering if I should wait for the Carrizo APU. I have been reading on HSA and APU, and think of buying Kaveri, but then I want to wait for the Carrizo APU in 2015.
TO me, some of the rumors and leaked die shots sound too-good-to-be-true... but a 30% increase in performance on the low-end sounds right--- maybe 10% on the high side?
Yeah just go with a 7850k for now it can always be sold on eBay later when you upgrade. The used AMD APUs have been holding pretty good value on eBay. I wouldn't worry worry to much about HSA right now. As great as it sounds it probably won't be utilized for a few years yet.
I think than a second rig can wait a little, I heard that 6 core cpus are coming out with carrizo. It may come in handy for streaming and video editing
