PowerColor PCS+ 290 and Sapphire Tri-X were $200 brand new almost 12 months ago. It was also very very easy to find a $250 R9 290X for months. See how super sales work?
Ya, and a stock
280X is 30.6% faster than a 960 with 0 overclocking. 280X has been available for
$185-190 for months, with lifetime warranty too. Never remember you bringing that up as a hot deal against any 960 though...
Besides a $650 980Ti, not a single other card released in all of 2015 was a good deal at MSRP. Even if R9 380X was $199, the
R9 290 can be had for $245 with $25 off $200 Amex deal. It's actually possible to get a reference 290 for
$175.
Reference
290 is 67% faster than a 960 and 43% faster than the R9 380.
In addition to that, 290 will slaughter a 960 in Star Citizen and the same fate awaits the 380X.
For anyone in the US, 290 continues to be the best overall gaming card between $170 and $250, with very few exceptions. R9 380X will not change any of that. However, in the rest of the world where 290 is either more expensive or it's EOL, 380X with $10-20 price drop and $20 rebate will be a strong offering against the 960 which will lose badly.
A max overclocked 960 can't even beat an overclocked R9 380, nevermind 280X or 380X. Maybe NV will man up and release 960Ti, the card 960 should have been all along.
