Hello. I am psypher246 from South Africa. Currently I have a 6990 and 2 x 5870's

I get 408 mhash on each 5870 (OC'd to 980)
I get 333 mhash on each gpu on the 6990

So in total doing about 1482 mhash

Should be adding another 5870 soon. Anyone in south africa interested in buying some of these with me:
