Thanks for the replies. I think I'll probably go for this card unless anyone has any other suggestions on something better for not much more money?
Elpollodiab,
Thanks for that link. After looking up the prices of better cards they seem to be a fair bit more expensive than the one I'm looking at. £140 would be my absolute maximum.
Iggy,
The 6870 is £70 more in the UK which makes it more than I was looking to spend. This was going to be put into a machine with an Intel E5200 @ 2.5GHz and 2Gig RAM.
Cheers guys
