Not new but returning

Good morning all,

I am not so much of a new member but a returning one. I have been away from pc's for a long time but looking to get back into things slowly. My old pc has died so I have another one. It is going to need some tweeks though if I am to get a bit more up to date.

Intel i5-4460 quad core 3.2ghz
12 GB Ram ( 2x6 )
no gpu at the moment
also need a bigger psu.

I am looking at Cx500 or 650 and a GTX 960

Whats your budget? I'd wait for the 480 from AMD over the 960.

Budget for a gpu is about £150

Is the rest of the set up ok

I am thinking of getting a 500watt CX500 or should I be thinking bigger for when I get a new gpu?
