That cpu will be bottlenecking it at stock speeds. If you can overclock it then you should, should be in the clear. The Phenom II x4 965 is a slightly better cpu and slightly bottlenecks that card.
Only if you're playing at maxed out settings on lower resolutions. If you play on high at 1080p, unless it's a real PC meat grinder type demanding game (Crysis 3, etc.) then you should be fine...if you bottleneck it wouldn't be enough to make a difference in your gaming.
Thanks! I guess Ill pick up a AMD FX-8350 and a XFX 7950
Not with that power supply you won't. Those power supplies sell for anywhere between £ 7 - £ 15 and aren't really able to tackle the demand an 8350 + 7950 combo would place on it.
