As long as it's a 6950, 6970 or 6990 regardless of model or manufacture it will work.

I understand your concerns but I am going to university in about a month so I need to save money but I can a second 6970 for less than £100 which should hopefully last me the next four years.Originally Posted by PontiacGTX
I WOULD sell that 6970 and buy a 7970 and then Cfx in a nearby future

that 7970 is very cheap compared to the quality it has
