Right first off im skint! I had a pair of XFX 275's running in sli and then my car gets crashed into and the person who did it disappears without a trace. Damage neck end of a grand. So I sell my 275's as they were worth a bit and as I needed a card I bought a cheap 9600 GSO!! Arghh. What a mistake. Poor performance to what I was used to and no fan controller either, just a 100% whirrr gutted. What can I get for around the £100 mark that will give me decent performance on my 790i board??
Sorry to hear about your troubles but you must've known that the 9600GSO is not for gaming.
A GTX 260 or 4890 ,as others have recommended, would be the best option.
