Okay just curious to what card is better. The windforce GIGABYTE GV-N780GHZ-3GD GeForce GTX 780 or the r9 290x. Also can you SLI a 780TI with just a 780? Like sli the windforce 780 ti with the ghz 780 windforce? Or would it be better to wait for non reference r9 290x and crossfire? Iv been with AMD forever and kinda would like to try nvidia. But If the r9 290x non reference benchmarks are as awesome as the reference benchmarks then I might have to grab them. have a XFx 7970 right now and will be running a 3 monitor set up with 3 of those awesome Korean monitors. Sorry for spelling im on my phone!
