Thank you. I've been gaming a lot with my current card (gf 8800 gts) and it's temperature can occasionally jump as high as 90-100 °C. Besides the occasional freezing (only in a few games, weird) I had no problems in the past 4 years.

Has anyone tried this? There are fairly cheap chinese development boards on the market with DSPs that can decode full-hd h264 streams. I wonder how efficient mining would be with these.

Yes, I realize this is not the optimal forum section for this kind of question but I can only post in the newbie section right now.

Yes, I googled the question and searched this forum but found no answer.
I have a ~4 year old asus commando motherboard with a x16 pcie gen1 connector. Are the newest cards (6990, etc) compatible with this? I've read that the connector speed doesn't really matter for mining, so I assume I'll be fine (if the card itself is backwards compatible, which I hope it is). But I don't know much about hardware.
