My current 7850 has been resident for approx 2 years and been ok for casual gaming, but a recent download of Arkham Knight has seen it struggle even reducing the resolution and with everything else either turned off or on low. There a few other newish games out there i'd liek to play too, so it looks like it's GPU upgrade time.... The system is a 4670 @ 4.2 with 8gb ram, a good seasonic PSU and a couple of SSD's What to go for? I've been looking at GTX 970's (EVGA SSC) or an R9 390. Is the stretch to a 980 or even 980ti worth the extra 250?? Is it even worth it with the rest of my rig? Any recommendations, comments etc welcomed!
