Amazon are taking back my SAPPHIRE HD 7970 GHz Edition 3GB GDDR5 VAPOR-X and giving me a refund, as they dont have the card in stock, will have to buy new card just wanted a bit of advise. do i get the same card or the Sapphire R9 280X X Vapor (Rebadge) also i dont know why but i save 60 quid if i buy the r9? dose anybody know why its cheaper and if its worth it. also what about crossfiring the r9's or is it more trouble than its worth? also i have been happy with my card till i had to rma it.. im not sure if i should stick with 7970 or upgrade to 280x or get a 290, thank you to anybody that comments or reads this =)
