I've come to the descision that I want to upgrade my 8800GTX, But fot the life of me I dont know what with! I have a 780i motherboard so I could use it as a physics card but I'm being overly tempted to go back to ATi, and in particular http://www.overclockers.co.uk/showproduct.php?prodid=GX-273-SP&groupid=701&catid=56&subcat=1752, As I've always used Sapphire when on the red side. I have also been tempted with a 6790 because of the price difference. I am happy to spend 200 - 225 maybe a shade more if it's worth it.
