Well after having issues with every version of the drivers, i decided to erase my system and start over from scratch to see if it was something with the nvidia traces from my old card, so brand new clean system 10.2 drivers and low and behold GSOD!!!!!!! Tried the other versions and the most stable are the 9.12 catylysts so im back on them for the moment 
Got in touch with Sapphire who gave me some excellent tips about trying all the different driver version including the beta ones (all still have GSOD) and reinstalling my system to see if that's the issue, i dutifully informed them that i had already done this they promptly (2 days) told me to return the card to reseller for RMA.
I have started this process by filling in the webform contact page thingy with all the details, my question is how long is this whole process likely to take in terms of getting a replacement card and is this really going to solve my issue?
