BTW, anyone have any idea of what type of hashrate one could expect from mining uTC with a sapphire radeon HD 7970 OC card? I have 8 of these and am thinking of pointing them at UTC.
Hashrate depends how much memory your GPU has.
For N-Factor 16 and 4GB VRAM: 400H/s < hashrate < 500H/s
If your card has 3GB you will get less than 400H/s
If Ultracoin gets back to NF15 your card will have four times more hashrate
