Yes, that is that one. And yes it's stronger, almost twice than your.
+card is having DP (display port is necessity for modern monitors above 24")
+Strix edition generate zero noise when is not under load
+supports Eyfinity (multiple monitors attached, like 3, one game screen)
+small pcb
+partially support even DirectX12, like all modern cards
-card doesn't support FreeSync
-it's in fact oldest from the new range, based on R9 265
Really the best point of this card was/is Black Friday price 100$, because here it costs normally about 70$ more, so it's a deal.
However it's mid range card, closer stronger cousin is
Asus Strix R9 380 which is also discounted on newegg to 140$. And which is also having better price-performance ratio, but it costs more. However it's a true gaming card, even if from entry level.
If you ask why Asus and Strix edition, that's because I didn't noticed any other interesting offers.
