Asus and MSI try to please too many people with the 4x mini-DP and 2x SL-DVI cards. I think by far the best solution is 6x mini-DP, and then 4x mini-DP + 1x DL-DVI for proper 5x1. 3x2 Eyefinity setups are pretty lame IMO.
On to the good news. It's a good thing Tahiti has a monster pixel clock as I've found I am able to push some serious bandwidth over single link DVI and my monster 24 gauge DVI cable:
That took me a few hours of tweaking timing's. I am literally within .02 MHz of not being able to run 120 Hz on my 700D. (256 MHz seems to be the absolute pixel clock limit on SL-DVI). It was a real nail biter edging back and forth with getting those timings to work. So now my entire Eyefinity setups is rolling along nicely at a buttery smooth 5400x1920 @ 120 Hz. Look's like the four Lightning's just may be keepers!
Amazing to hear man :D
I can't wait to get my hands on a 3+ miniDP 7970. I think that making future cards miniDP only with adapters would not only be beneficial to the enthusiasts who need it, but also in pushing the new technology further in to mainstream and reducing costs for everyone to adopt it.
