The biostar board has the #1 & #4 spot on the 3 cpu chart and the #1 spot on the 4 core. I have one, but I don't know if I would recommend it. It seems to OC well but it has no heat sinks on the MOSFETs and a passive sink on the NB. I acutally ran into trouble with 75C on the NB and system lock during stability testing. The temps, I think, were my fault as I had my 25" monitor pluged into analog and dvi (you can't see the bios screen with dvi and have to just hit del when your keyboard flashes). It doesn't matter for me as I'm going with a custom watercool setup so I just have to get the parts together. The bios is labeled kinda weird, but has options for clock and voltage on IGP memory, IGP gpu, NB, SB, pci-e, cpu, memory, and HT.
Most people, I think, would recommend the gigabyte board and it has a current rebate on newegg that makes it only a few dollars more than the biostar.
I bought my Biostar late last summer and at the time felt it was the only GX series board I could afford. I don't regret that decision much but have added a HS to the MOSFET and NB areas to more adequately cool it for OC'ing. With the added $ I put into it perhaps I should have gotten the Gigabyte instead. No doubt its a much better board.
Well said by both. I have the biostar ta790gx and I glued some passive sinks to my fets with some AS thermal adhesive, I also put a small 45mm fan on the NB and it dropped temps from peak 55C to a peak of 41C. The mosfets still do get hot to the touch when running 4 instances of prime, its a little scary.
