I just pulled the trigger on a new rig, parts listing via newegg:
http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=18407306Cooler Master HAF 932 case
G.Skill ripjaws 16gb (4x4) DDR3 1866 memory
ASRock A75 Extreme6 motherboard
AMD A8-3850 llano apu (has radeon 6550D gpu)
3x xfx 6950 gpus (I believe it's reference, so can unlock shaders to 6970)
OCZ Agility 3 120gb ssd
Antic High Current Pro 1200w
I know the memory and ssd are overkill for mining, but I plan to use this for gaming as well. Later I'm going to build a dedicated miner. I'm thinking about leaving the cards separate when mining and switching them to Crossfire when gaming, but not sure how realistic that is. Anyone know if there's a way to do this via software and if not, just how troublesome it would be to do manually each time?
The one thing I'm worried about is the heat. Does anyone else have this case with this many cards in it who wouldn't mind sharing their experiences? I'm going to see how it goes for a week or so, then I may switch to liquid cooling (again, overkill for mining, I know).
My order will probably be processed sometime tomorrow, so I have until then to make any changes.
Thanks for your indulgence!
