Oh, well generally the 900 series have better usb 3.0 support, official sli support, and better raid for ssd users. Just to name those I know.
I don't want sli , I'll be using only 1 gpu.
I dont need raid either.I have 1 internal hd other external.
So these 2 factors are excluded.
But what do you mean by better usb 3.0. ?
I mean both chipsets support usb3.0 so they should work the same way.
How come 9 is better than 8?
