I've been following the graphical Hierarchy chart on toms hardware for quite awhile waiting to upgrade but there are only 4 cards above mine to upgrade to. My concern is that the next batch of cards might work better with whatever Direct X that came with Windows 10 and possibly be more optimized for 4k (Planning on upgrading my monitor as well sometime soon or get a 2nd one anyways) although i'm not planning on upgrading to Windows 10 for some time. Is it time to upgrade or should i wait for the next wave of cards?
