Does it matter that its a refresh with tweaked bios , drivers and power consumption?
Its arguably better value than the 970 which is nvidias product at the same price.
Slightly better performance even when overclocked ( to be fair if you can do 1500 mhz instead of the 1420 or 1440 mhz on the video you can match them).
Same price , and you get a bigger bus ( 512 bit) and double the VRAM which is always never bad and will be useful even now at 1440p+ , not to mention VRAM requirements
increase year after year so having a 8 GB safe zone is pretty good.
We know from 290x 8 GB reviews that the card can actually fully use the 8 GB of VRAM . Linus used a 8 GB 290x on one of his videos ( I think it was the 12 k setup).
I think its just great value for the price , 330 dollars on newegg.

The 290x 8 GB is MORE expensive.
Its hard to argue its very good value for a GPU.
Now if i could say the same about that damn Fury X.
