ok i currently have a asrock p67 extreme 4. it only supports dual sli or quad through use of sli 690s. i was going to go that route but realized the 4gb vram is shared and thats less than i have with my 570s so whats the point. so im thinking of 3 4gb 680s instead which isnt supported, which brings me to my questions. should i wait till 790 comes out and hope it has 8gb, which i dont see happen. or i could get another 1155 socket mobo that will support quad sli, but im wondering if that would be a waste of time since the 2500k is getting old. and lastly i could just get 3930k but i read its not too big of a performance leap over what i already have. so any help, comments and suggestions would be appriciated. ive been thinking about this for months now, and have no idea what to do. just to let you know, my pc is used for 80% gaming, and at 5912x1080.
