I just got a new PC, built it myself from a kit:
APU: AMD A10-7700K Kaveri 3.5GHz Socket FM2+ 95W Quad-Core Desktop Processor with integrated AMD Radeon R7 GPU
VGA: PowerColor Radeon 7870 Ghz edition AX7870 2GBD5-2DHV4E, PCIe 3.0 // Memory: 1200 Engine: 1000
My settings in cgminer currently (NOTE: I am still tinkering with the settings as I just got this miner fired up 2 days ago:
--intensity 12 -T -g 1 --gpu-memclock 885 --shaders 1280
Kh/s with these settings: just a hair under to a hair over 300.
I can tinker the intensity to 13 or 14, but haven't tried about that. I can memclock at the highest of about 925...though 885-900 seems to be best for me. Anything higher or closer to 1200, and I lose an astounding amount of kh/s. I haven't really played with any other settings yet as I'm really quite pleased with my kh/s at the moment.
If anyone has any other advice, I would love to hear it.
