is a gtx 760 good enough

Solution


wait a couple of years and then upgrade to one of the newer videocards (there are new ones mostly ever 1-2 years)
at the moment it is good, it will probably be able to run new games for a year or 2.
if you can spend a little more money, then get the gtx 770, which will be more future proof and will also run games at higher settings.
Make sure your PSU supports your upgrade though, for the gtx 770 you need 2x 6pin pci-e slots and 42 amps on the 12volt rail.

hope that helps you
 


If you don't play games that much then wait till you feel like its a pile of crap and then buy a new one which will be much better than anything right not ( not everything but better than these two cards )
