The 980ti is a monster and the titan is just that, a titan. The 980 is a beast too, overpriced but a beast non the less. However the gtx 950,960, and 970 arent worth buying anymore.
Lets go from the top down,
the r9 390 > gtc 970 AND the r9 390 is CHEAPER
THe r9 290 is slightly more expensive than the gtx 960 4gb AND beats it handily
even if we go price comparison
the r9 380 > gtx 960 at BOTH the 2gb and 4gb price points
as for the gtx 950 the r9 285 is THE SAME PRICE and is better than the gtx 960 let alone the 950
IS there anything I am missing or does it seem that from a price to performance standpoint team red is winning in the sub $250 price range?
