Definitely not much. Maybe you could get them playable with the lowest possible settings but it still wouldn't be great. Not only is your card a few generations old, it's the second to lowest end card of that generation. As long as you're not playing at really high resolutions where the memory would come into play, you can still get away with an older card though. I have 2 GTX 660 TI's in SLI & a 4790k and have no problems running anything at 1680x1050 & 1920x1080.
