AMD would be making the R9 290X the new R9 380X and the R9 285 the new R9 370, and so on and so forth. However the rumour mill suggests that AMD’s changed its mind, apparently – and every single cards in the new 300 series will be a new one. Higher ups at AMD have apparently demanded that the company launch with a full new solution, rather than a brand new high end card and a re-appropriated middle end.
All this is good, but AMD needs to move damn fast if it is going to stop Nvidia's latest surge of market share.
