Ok, so the top one, with the 2 lines above your cgminer.exe....... cmd call is what you want to use. The reason you're hashing so low is because of your low TC. Raise your TC to 24,000 to start, and then go up from there until you find the right settings. You needed those 2 lines you now have to increase your TC above the default spec limit. I had the same issue on a set of my cards. Increase your TC to 24000 and your intensity to 17 to start, and then just tweak from there. Also don't be afraid to strip a lot of those settings your using there as you can control or keep an eye on some of it yourself. I've found most aren't needed personally.
https://litecoin.info/Mining_hardware_comparison is an excellent source of information as people have their config calls listed there. You'll see most aren't that long at all. I started there though and tweaked a few my TC and Intensity until I found the best combo for me, you shouldn't have any prob doing the same now.
Edit: Ok, so I just saw you can't get past the TC limit, which is odd with you using the proper:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
The only thing I can think of is to run the actual batch file itself and insert those 2 lines above it, or and you can try this either way, but maybe right click and run as admin. Maybe since it's a fresh build you need to set the environment variable and you have to "Run as Administrator" to do so. Just seems odd that you'd still be getting the TC error with those 2 lines in your batch file. I had the same problem on the one I just built, but as soon as I added those to the batch file I was good. I can't say for sure I didn't right click and do that once or twice though. I was getting pretty frustrated as I'm sure you are, and I was trying tons of stuff. Good luck though and hope it works out for ya.
