ive been reading alot on the current situation with the 970 having 3.5gb of memory and another .5gb being very slow or managed a different way or something like that. do you think that will matter? currently im on a 1080p tv and was wondering if it would be worth it to get a 1440p monitor and either stay single card or sli my 970, i dont plan on doing 4k for quite some time and by then ill have another card.
