Thanks for your reply,
That's great to know. All I want is for it to play blu-ray movies without freezing and stuttering like my current pc. Angry birds will be enough for me.
I currently have this PSU:http://www.ebuyer.com/271798-corsair-430w-v2-cx-series-psu-cp-9020046-uk
Will this still be alright? I won't be overclocking.
