I am interested in this argument.
I have an HD 7970 and was thinking splashing out all of another £220 on getting a match for it and crossfiring them, should I feel the need for more gfx horsepower. From the benchmarks I looked at, this would give me way moer horsepower than 780 GTX, TITAN, or R9 290X at a fraction of the price......
....but what is this about stuttering?
Are the HD7000 series still suffering from stuttering in multi-card mode. If so, are you saying this isn't the case with Nvidia multi-card setups?
I have a GTX780M in my laptop. First time since Geforce2 days with an Nvidia card and got admit I find the drivers much nicer to live with than the AMD equivalents and possibly games run smoother in general than on my HD 7970 as well, although the HD7970 is still a much faster card capable of markedly higher frames.
However, with certain games, I get stutter with my GTX780M.....this can also depend on what monitor/TV screen I have my laptop hooked up to, but surely it is the drivers job to make sure this don't happen. So if I can get stutter with a single Nvidia GPU, I would imagine there is still plenty of potential for multi-GPU stutter with Nvidia.
