For everyone saying something negative there's someone else saying something positive. Can't argue against balance surely?
Maybe if everyone stopped saying positive things people would stop saying negative things?
These are the ones AMDMatt listed when AMD released the 8GB 290X:
Battlefield 4 (Mantle)
Dragon Age (Mantle)
Thief (Mantle)
Hitman Absolution (DX)
Crysis 3 (DX)
Shadow Of Mordor (DX)
COD Advanced Warfare (DX)
Watchdogs (DX)
Wolfenstein (DX)
Of course really we also need to run a 4GB 290(X) (or possibly 980) in these to confirm you can recreate the issues AMDMatt had when he produced this list. Saying the Fury X doesn't have issues in these games and therefore HBM solves anything only proves that if a 4GB card does still have issues, otherwise there may have been game patches (or drivers) that helped instead.
Ive got everything on the list expect watchdogs so will run some tests over the weekend on my 4gb r9 290x with 14.20 drivers and see what happens as a benchmark to the fury x when they come out.
