Our settings for DiRT 3
DiRT 3 at 4K resolution isn't showing as much of a difference between the GTX Titan and the other competitors with the HD 7970 something around 10 FPS slower.
All of the frame time results are consistent in DiRT 3 without any stutter or runt problems.
The GTX Titan averages about 53 FPS at 3840×2160 with all settings maxed out and the Radeon HD 7970 is 18% slower with an average of 45 FPS or so. The GTX 680s, in both 2GB and 4GB variations, fall to 40 FPS.
Noting the scale on the left of 3 ms maximum, there are no frame variance issues to speak of here.
CrossFire continues to have problems with runt frames, resulting in the much lower observed frame rates. With that in mind, the GTX Titans are obviously the fastest options here with the GTX 680s in SLI coming in pretty closely at second place.
The frame time graph shows you the mess that is AMD's CrossFire producing alternating runt and large frames. Even if the animation is "smooth" you are getting much lower observed frame rates than FRAPS would be reporting. The Titans and GTX 680s produce very good results with only the occasional spike.
Now we're talking! DiRT 3 at 3840×2160 over 90 FPS is an outright incredible experience! The GTX 680s produce another great experience with an average at 75 FPS.
Frame variance is pretty low for all three NVIDIA configuration but things look bad for AMD's Radeon HD 7970 after the 80th percentile.

I got a seiki 4k tv 39in led
I got a seiki 4k tv 39in led and with vsync off yes I get screen tearing in some parts but with the 7990 it scales extremely well. It looks fantastic batman arkham origins looks phenomenal and it plays great. Crysis 3 I had to limit to medium settings and it played great as well. As long as you disable vsync you’ll get similar fps to playing in 60hz. I got the tv on sale at tigerdirect for 300 bucks! Hell might as well try it! If you have the gpu to push it you will see a difference. All of my friends that came over did they were highly impressed.
