Didn't mean to open that can of worms again, sorry guys! I do have some playability issues in SOME games, not all and that is relative to my flatmate's 4670k.
I have someone to hand my 8350 machine on to for a donation towards my intel processor so won't be a total waste of money they are also desperate for a machine and will not be looking towards xfire in the future, unlike me.
The other reason is that I'm very tempted by a small form factor pc which, with the current mobo selection, i am unable to do with AM3+
Ideal if you have someone to sell it onto, the extra performance and much lower power on the 4770K etc use make it a worthy upgrade. If you buy into Z97 chipset you have added future upgrade as well.
Go for it.
