Which graphic should i purchase, either Gigabyte ATI Radeon HD 5770 or Sapphire 11168-15-20R HD 5670?

Cant decide between either:



Gigabyte ATI Radeon HD 5770 1GB (around £120)

OR

Sapphire 11168-15-20R HD 5670 1GB GDDR5 Ultimate Edition Graphics Card (around £85)



Im not really a serious gamer, but i do like the occasion game release e.g. witcher 2, black ops, dead rising 2

and of course i watch a few hd 1080p videos.



I am currently using a 9600gt, which is a little noisy seeing as the rest of my pc components are virtually silent. So thats why i am going for fanless video cards with heatsinks.



Thanks people.|||You'd be better off with the 5770 if you want good graphics.



5670 if you dont care about the graphics.





Make sure your PSU can handle them.|||The witcher 2 is very demanding. 5770 at least!
