I have a SLI compatible motherboard, power supply and I have an SLI bridge and plan to get another Gigabyte Windforce GTX 560. The one I have model name's name is GV-N56GOC-1GI REV:2.0 and the one I found and want to get is a GV-N56GOC-1GI REV:1.0 will this work okay with any performance drops? Thanks in advance for any replies.
