You won't see any problems with the newer pentium the person who talked about them being hot and all was talking about the older pentium cpus. You should be fine with that gpu because you are using a lower power cpu and I am sure you don't plan on some massive overclock on the gpu. You can still overclock the cpu and you shouldn't have any issues.
