As a new member here, I'm required to post here, but I do have a few questions concerning mining with a 7950. My previous 5870s were easy to mine with, but I've downsized from a TJ07 to an ITX build and am waiting on my Bitfenix Prodigy, so it's a different game now.

I am currently using GUIMiner (v2012-02-19) and SDK 2.7 I believe. I am using the AMD 12.7 beta drivers and with an OpenCL miner my 7950 @ 1300/330 is getting about 660Mhash/s, this is with no flags. If I try to add other flags (-v or -w flags) hash rate goes down.

What direction should I be going to get better hash rate? Should I step out of GUIMiner and go with something else? I've seen 7970s get 650 easily with much lower clock rates, but I would assume a 7950 @ 1300 core should at least reach 700+Mhash/s.

Any help is appreciated and I apologize if I broke any rules with this post.
