Hey guys so im thinking about upgrading my card soon and i was wondering the difference between PCI 2.0 x16 and 3.0 I have the Sabertooth mobo and im a bit confused on the matter. Are these two Compatible or should i invest in a new motherboard. Also is the 980ti 8 pin or 6 pin, i might also need to invest in a new power supply.
