I can get the 7990 Malta sapphire past 1330 mh/s, the Sapphire 7950 I can get to 570-620mh/s, the xfx 5850...well it just kinda sucks at OC even though it runs very cool.
This post is not to brag about hash rate. I just want to show it certainly is feasible to run a couple 7990 or 7950 cards in one rig and at nice comfortable temperatures with only stock coolers. Please note I have the 7990 Malta at stock clock fo 1000mhz. I can push it past 1200mhz if I want for more power.
