Yeah you read that right - don't laugh 
Looking to upgrade my graphics card and been out of the loop too long. Mainly looking to be ready for GTA V (specs unknown) and take advantage of cranking the detail on some of the games I've picked up in the Steam sale.
I was looking at this: http://www.overclockers.co.uk/showproduct.php?prodid=GX-175-OK
which seems to be pretty good for the price (I'm willing to spend approx. £200) but would it run OK off a 620W Corsair PSU (Modular)?
Rest of the PC is nothing special:
q6600
4GB RAM
24" screen but more than happy to drop resolution to bring performance up
Would that fit the bill nicely or should I be looking at something else?
