Ya just 1080p monitors. Can the 780 do 6 monitors or just 4? (The last video card I bought was a GTX 460 so my info is way behind) I thought only Eyefinity supported 6 monitors on 1 card?
My problem with the r9 290 is that my daily driver is Linux and AMD has garbage support. It's supposedly getting better, and fairly decent for the more expensive cards, but the last 2-3 mid ranged cards I have had in the last 3-5 years have sucked. I can either have 2 displays with no sound and no tearing or I can have sound with no tearing. Granted I haven't tried AMD in over a year now, but it seems to be to be an awfully big gamble on such an expensive card (read anything more than $50 is too expensive to me if experimenting with video drivers).
I will take your feedback and do some research, maybe I will post in the Linux section here and see if anyone has decent experience with AMD nowadays. Conversely, I have yet to have a single problem with nVidia's drivers ever. Sure they arent perfect but my stuff always works
