the two slots are identical and backwards compatible. the only advanteage that V2.0 has over a 1.0 is that it can send moer power via the motherboard, and supposedly has a higher bus rate. you will not notice any difference between the two.
they do have higher bandwith the double of v1 there is just very little use for it with our current cards even cards like gtx295 have very little use from it
may i ask something. what if the one card is used in 1.0 instead of 2.0 , like for example if i use 4670 on 1.0 will its performance be almost half of that on 2.0?
what will be the diff in performance?
Yes, as long as your board is 1.0 compliment. Some early PCI-E boards don't adhere to standards too well so they can have problems, but that's really pretty rare.

No. As long as the bandwidth used by a card does not exceed the theoretical bandwitdh of the slot, you wont see any performance losses.
