According to Benchmarks:
Wolfenstein: The New Collusus - 4k Ultra @ 92fps
Shadow of the Tomb Raider - 4k Ultra @ 45fps
GTAV - 4k Ultra @ 55fps
Forza Horizion 4 - 4k Ultra @ 63fps
Battlefield 4 - 4k Ultra @ 60fps
Most games get you in the range of 60fps on 4k.
See this honestly makes me sad. The 980 was what? 3 years ago at this point? And I was running maxed GTAV in 4k at an unstable 30-40fps. 3 jumps later in tech and still not at 60fps is eh.
Generally I don't like to upgrade cards until the new one doubles the performance of the previous one. So games that were doing 30fps at 4k are now doing 60fps. This seems pretty close, but the fact that it's not clear and stable there is a bummer.
Also I have 2 980GTXs and been running them SLI so for games that support SLI basically been getting like 1.5x-1.75x 980 performance already so this isn't much of a leap. Now since 75% of games do not support SLI (maybe more like 95% these days don't support it), yeah it's still a good upgrade.
I'll probably jump in on these models, but might wait one more year to upgrade.
The game that taxes my rig the most is Hitman 1/2. I tried playing the new Bank map and I don't think I'm even hitting 30fps at 1080p without SLI (haven't tried SLI but I think Hitman does support it and it helps). I usually keep SLI defaulted off and only turn it on for specific games when I need the extra performance because SLI on fucks up a lot of games.
How does my cpu still hold up these days? I'm running an i7-4790 at 4ghz w/16gb ram. Wondering if I should just do a new build from scratch in the next year.
