Graphics Replacement for 8800GT: What to buy?

Basically my 8800GT has broken and is out of warranty so I'm looking for a replacement. I have a budget of about £120-£140 max. I'm thinking a ATI HD5770 seems like a good option. Any other ideas...?

 

Thats the card I would go for at the present moment in time. The drivers have now being sorted out

 

Cool. Can anyone reccomend a particular version of the 4770?

 

I've just got the Sapphire 5770 (not vapour-x ver) and its unreal, I came from a 1900xt so my upgrade was pretty drastic, but its so cool and so quite!

 

Hm. I think I'll get this. Are XFX good for warranties/in general?

 

Purchased. Thanks for the responses.

 

I have an XFX mobo, and a graphics card, and have been really happy with their support. When a storm fried the motherboard XFX shipped my a replacement the day I called them, they sent it before I even shipped the broken one to them. Granted the replacement was broken and I had to get another one (but I'm almost positive that was my fault).
