PCIe 3.0 and 2.0

Good Evening, could someone tell me if it would be wise to use a 3.0 card since my mobo says its PCIe 3.0 ready if it uses a 22nm processor (the i3,i5,i7) but since i use a pentium G860 im not sure, as i've asked on a hardware shop near me and the guy said it would mess up, where here i was "told" i could use a 3.0 but i still wanted to be sure

This is the MOBO i have : http://www.asus.com/Motherboards/Intel_Socket_1155/P8H61M_LE_R20/

P.S. Altought mine is REV 3.0 it still says its PCIe 3.0 ready so i wanted to know since i have a budget around 100~150$ for a card

    Ok, your CPU is not 22nm, yours is 32nm. You'll need a BIOS update to be able to handle PCIe 3, as well as a CPU upgrade. You could still use a 3.0 card, it'll just run at a lower interface bandwidth. You can also use a 2.0 card readily (and probably a better match for your CPU).
  2. PCIe 3.0 is useless right now, 2.0 isn't full maxed this generation, it will probably be another generation or two before it starts maxing out, and by then 3.0 will be standard. You can use a PCIe 3.0 card on a PCIe 2.0 or 3.0 slot. So feel free to buy whatever card you want.
