PCi e 2.1 or 3?

[Ravyu]

Note: I am not planning to upgrade to the GTX 600. GTX 700 will probably be the next time i am upgrading


Ok here is my specs:
i5 2400 3.10ghz quad-core
8GB RAM
GTX 560 non ti
630 watt power supply
Z68-V Asus motherboard

I realized my Z68-V motherboard is already outdated, only having a pci e2.1 express slot. My question is, in two years time will it be ok to upgrade to pci e 3 or do it right now. The next GPU i want to Ugrade to is a GTX 760ti. Will it do me justice?

There is no performonce improvements for graphics card with PCI e 3.0, they said that with IVY bridge processors there will be but i didn't see that yet.

so no need to worry about pci 3.0 right now, and also when the GTX700 came, everything will be different maybe there will be already pci 4.0 so no need buying it if you are not going to use it right now (if you would use you teorycally would need a ivy bridge processor)
