My 280x runs it on ultra 1080p 60 fps too, without overclock @disqus_oOKHK2To8C:disqus
No it cannot do that on solid ULTRA 1080p steady 60fps not possible on that card. did you overclock it, fucker?
im using a pre-build Hp, so i got the 285 cuz it used less power, i returned it and got a 280x 1100mhz for 100 bucks less, and it preforms MUCH much better giving me full 60fps on GTAV on 1080p ultra settings
Definitely not ''way '' better
yeah i've read that too. but ended up buying 280 and oc'd it. it uses more power but performs way better than 285
After reading the comments below, I looked into the idea of getting the 280 (not x) and overclocking to match a 280x and comparing either of these to the 285. After reading this article, http://www.tomshardware.com/reviews/amd-radeon-r9-285-tonga,3925.html, my opinion has changed. The 285 uses the Tonga GCN architecture, not Tahiti. So the 285 is quite different inside from the 280 cards. Please read the article above to understand what is different.
