This is exactly it, if I was just gaming then I probably could just keep the phenom but I want to do a lot more 3D modelling which I really enjoy so it will help with that.
I think mine is the GA-990XA-UD3 rev: 3.0, I did think about what your saying not long ago and wondered if I was going to need a board upgrade, maybe the Gigabyte GA-990FXA-UD5 or the Asus Sabertooth 990FX, I know the sabertooth is better but, and this may sound stupid, I really really do not like that gold/brown colour, it is hideous. Now, if I look at upgrading the mobo it is going to start raising the point, why dont you get a socket 1150 and get an Intel, well the only Intel worth getting over the 8350 is the 4770K which is still £100 more for something I don't need.
