Title: Single Core Celeron CPU running two running two ATI 6990 GPU's Post by: matthewh3 on February 07, 2012, 10:31:21 AM Hi I've got a old SLI enabled Intel Q6600 quad core cpu PC. Was thinking of getting two ATI 6990's or 7990's when there out. My question is would a Celeron 420 single core CPU run the GPU's OK? Was thinking of swapping the Q6600 that runs at 105W for a Celeron 420 that runs at 35W. Would the Celeron run the GPU's OK?

Damn it still draws a lot of power; but i've no other choice since my motherboard can't run a 420, and a 420 is quite expensive compared with a 331 Title: Re: Single Core Celeron CPU running two running two ATI 6990 GPU's Post by: BinaryMage on February 07, 2012, 04:22:52 PM Yup, needed CPU power for mining is minimal. (Just make sure to run Linux; I would suggest BAMT)
