I know there are probably quite a few of these on the forums so please don’t complain about that. I also ask that this thread does not become another ASIC/FPGA/GPU argument.
Anyway, I’m in the looking for a new card for my main gaming rig, I have three 1680x1050 HD monitors that I currently have hooked up with two 5830s in CFX. I’m looking to replace these cards with one ‘higher end’ card that is capable of supporting my triple monitor setup, both for productivity and for 5040X1050 gaming, my only other stipulation is I want it to be able to bitcoin mine while idle. I’ve mainly been looking at the new 7xxx series. The main one that has caught my eye is the XFX cards, but I would be open to other brands for better performance or specs.

I have a dedicated miner that seems to be giving me some grief. I know that a 5830 should get somewhere in the high 200s low 300s for their hashrate. My problem is that the 5830 in me dedicated rig is only reaching 179 Mhash/s. In my main computer I have 2 5830 in crossfire that can reach 570 Mhash together (Maybe more). I've put the cards from my main computer into the dedicated rig and all of the cards maxed at around 170 Mhash, but when I moved the cards back into my main rig they went back to 280 Mhash. I've switched slots on my motherboard and I've even tried different power configurations from my PSU. I am currently running v11.5 Drivers with v2.5 SDK.

Any help would be appreciated.


MSI 890FXA-GD70
AMD Sempron
4GB DDR Corshair Ram
(1) 5830
Cougar CMX 1000w PSU
OS: Windows 7 64-Bit

UPDATE:
I ordered a new Mobo from Newegg and I installed Windows 7 64-Bit. I'm still only getting ~160Mhash/s when I should be getting somewhere close to 300+.
