Will a PCI Express 3.0 video card work on a PCI-E x16

[Fleshless666]

Suggest me the best nvidia card i can use with my mainboard if no

My current card is using a PCI Express 2.0 x16 slot and there's no problem, so there would probably be no problems with the PCI Express 3.0 x16... Am i right?

No problem at all.
It will not affect the speed too.
