OK. So just because everybody here was so supportive with others, I have managed to set my miner in surprisingly optimum parameters. (after a few hours of hard tweaking ofc!)
So just thought of putting these settings up for anybody that has a similar rig!

Miner rig setup:
Celeron 2.7
Extreme4 Mobo
2x4gb Corsair Vengeance
80Gb sata hdd
3 x 7970 Sapphire Vapor-x (BIOS reflashed to OC) 11197-12

Vertcoin miner 0.5.3 Setup:

color 02
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

vertminer.exe --scrypt-vert -o stratum+tcp://spain.speedhash.eu:21492 -u xxx -p xxx --intensity 13 --lookup-gap 2 -g 1 -w 512 --shaders 2048 --thread-concurrency 8193 --gpu-engine 1070 --gpu-powertune -20 --gpu-memclock 1490 --gpu-threads 2


Gives me constant 384/367/384 Kh and I'm REAL happy with these settings.



If I've helped anybody with these please feel free to donate, and have a Great Day!
