thanks for that shout, tbh never really done much background into the 5770 I always assumed it was the same GPU structure as the rest of the 5XXX series ... I didn't realise it was essentially a juiced up 4XXX.
I think in that case it's sound advise .. I'll try a 5870 and then just return it if I still have the same compatibility issues and crashes.
Like I said, I don't mind who makes the card only that it works, has DX11 and is good value for money. I wasn't prepared to risk buying another card from the same series but as you said they are more different than I realised.
cheers
What issues and crashes? Had 3 5770's in various machines which are well used and have very few issues and no crashes?
My 5870 with the new drivers is great, and I've had next to no issues with it.....
