Upgrade CPU or GPU first

I'm at a dilemma. I currently have:
i5 750 CPU
Nvidia GTX 560ti
Biostar TH55B HD ( PCI-E 2.0)

Should I upgrade my first mobo/cpu to get 3.0 support, then upgrade my GPU next year? I'm curious to which will get me more performance. If I get a GTX 660 or 680 will that last me 2 or 3 years? I'd hate to buy a 200-300 dollar card then have to get a new one a year later. Currently, I'm getting lag spikes from low frames on BF4 on max settings. Though it only happens with massive environmental destruction is happening.

    Can I get a 760 with a PICE 2.0? I don't have 3.0

    The PCIe std is backwards compatible and the even the most powerful cards hardly get bottlenecked on 2.0, here example HD7970 and GTX 680 http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI-Express_Scaling/23.html
  4. Yes, most cards do not take advantage of the 3.0 anyways. If there is a slight disadvantage, it will be very little.
  5. Oh wow, had no idea they were backwards compatible. Yeah, might just get the GTX 760 if there isn't a huge difference from 2.0 to 3.0. 780 is a little too pricey for me. Thanks a lot, good information to know.
