What the hell is an R9 M370X and is it worse than the 950/960M everyone was predicting?
EDIT: still Haswell?! Ok so this is a non-upgrade filler until Skylake later this year rather than next.
I believe they're both similar in performance on paper. Skylake may not be until early 2016. If this current spec bump would have been released earlier in the year then Skylake may have been possible by the end of this year. An announcement by end of year may be more likely.
