I'm wanting to get a new Nvidia 680 motherboard. I narrowed it down to the eVGA motherboards. But I noticed that there are two different Extreme motherboards. They are listed below. My question is did the A1 verison replace the AR verison? Is the A1 still a good board to get?
eVGA 122-CK-NF68-AR
eVGA 122-CK-NF68-A1
eVGA 122-CK-NF68-AR
eVGA 122-CK-NF68-A1
