I have just swapped out my 760 for a 770 as I was getting poor benchmarks and visual distortion. However the 770 is performing better but with similarly poor benchmarks compared to similar systems. My unigine heaven results (1080p/ultra quality/extreme tesselation/8xAA/vsync off) are;
FPS 36.5 Score 919 Min 19 Max 63.5

The image also flickers a lot when it switches viewpoints

My Firestrike (non extreme) benchmarks are scored at 6675 : http://www.3dmark.com/3dm/3574826

On this benchmark the screen distorts a lot as if viewed underwater.

The results are better than my 760 obviously but underperform relative to the 760 compared to other systems. My spec is 4670K/GTX 770/ Asus Z87 K/ 8 Gb Ram/ Windows 8. What could be causing this? PSU/mobo?
 
Solution
you monitor not prevent higher than 60 FPS, it will however, Tear when the frame rates exceed the Refresh rate. That will give you the warped effect where the top and bottom of image doesn't align.

In all the bechmarks my max fps is relatively low compared to other scores;

Heaven 63.5
Valley 65.1

I have turned the Vsync off in Nvidia control panel. Is my monitor the limiting factor (Asus VS239H IPS 60Hz)
