Hiya, After having to send a faulty 7850 back for a refund I am now shopping around for another upgrade to my aging 5750 I have found a Saphire HD7870 on for £160 which I consider to be a fairly good deal - However I am not sure whether I can power it and a 2500k with a 530W Thermaltake PSU. This also raises the question - Should I purchase it with the 8000 series supposedly on the corner. Am I likely to find a 8000 series GPU which it better than the 7000 series I am looking at within my price range (<£160) in the next couple of months?
