Here are my results with PNY VCGGTX7702XPB-OC GeForce GTX 770 2GB.
Rig: i7-2600K @ 3.4Ghz, 16GB RAM, Intel MB H67 (no overclock, no need when you go GPU mining).
The GTX 770 runs at GPU core clock at 1241Mhz, Memory at 1800Mhz, GPU temp at 73C, FAn at 63%, GPU load 96-98%, Video eng at 0%, Power at 61%. VDDC 1.2V (All GPU-Z info).
No OC done, but this PNY does it on its own I think. With this cuda miner the GPU runs quite cold, compared to the script gpu miner and the power consumption here is quite low, with the script cuda miner it does to 90+ %.

Results:
version 0.3 - fluctuates from 950 c/m to 970 c/m, Uses 900MB GPU ram
version 0.4 - fluctuates from 920 c/m to 1020 c/m, Uses 1100 - 1200MB GPU ram

Someone asked how much PTS can do, I am getting from as low as 0.04 a round(block) to as high as 0.07 a round(block) with the above setup and v0.3 of the miner.

I do see a message before or after each submitted share:
[Worker] collision found: 20596710 <-> 57587360 #26536 @ 1390832977 by 0

Can you tell me why there are collisions all the time? I looked for the source to see the conditions for this message by cannot find it.
Is there a way to stabilize the version 0.4 rate in the higher range ?

Thanks for the great PTS cuda miner and all the support!
