I'm shopping around for a new custom build PC at the moment and can't decide whether to go for a GTX 680 or 690.
At the moment, a 690 would be overkill because I'll only ever be using one monitor and most likely 1900 x 1080 for 3d Vision...maybe higher res later on. But I don't plan on updating my system for another 4-5 yrs, so was thinking of the 690 as future proofing as far as possible (i.e. no idea what the next gen consoles specs might offer), for when a 680 can no longer cut it.
So...is it worth going for the 690 while I can afford one, or is it a waste of money/resources?
Any thoughts appreciated...
