AMD Radeon R9 390X
The R9 390X is the R9 290X with twice the VRAM (this seems unnecessary) that is clocked a bit higher alongside a slightly higher core frequency. On paper this means a 5% increase in GP/s and a 20% greater memory bandwidth.

The R9 390X carries an MSRP of $430, 30% more than the current R9 290X for less than 10% additional performance. This is still a better value than the GTX 980, costing 14% less for just 7% less performance, but it's hardly enough to get us excited.
