I was messing around testing different OC settings and then i restored everything to default values (before OC) and did complete reinstall for driver and miner.

Now my Mhash is not stable, it jumps between ~120 - ~280? Any idea what might cause that?

I bought HD6970. I know it's not best money wise for mining, but it was best i could find without placing order.

Installing it soon and if my PSU can handle both cards (5850 and 6970) i set them both in my machine. If not, then i have to buy new PSU so i can use 5850 too.

6970 is running now, what flags do you recommend? I tried those found in hw comparison page but not really difference with or without those flags? I use GUIMiner.

Didn't have enoough room for 5850, i'm buying new PSU and put it in other comp.
