Its already happening - on HUKD people are thinking the GTX1060 3GB and 6GB are the same cores and are using GTX1060 6GB review numbers.
It makes me wonder whether AMD has missed a step here - they should have sold the RX470 as a RX480 4GB for £199 and they would have been quids in!
A £200 3GB "performance card" in 2016 - its almost like Nvidia and AMD are trying to upsell the cards in the £200 to £300 range now.
This whole new range of cards from AMD and Nvidia are slightly dissapointing and it makes me wonder whether I should have just picked up an R9 290 or GTX970 last year now,as they could be had for around £200.
