I plan on doing triple 1080p 144Hz monitors but only playing the game on the one middle monitor, and then having the other two screens monitoring the video capturing etc. Should I get the 4GB models because don't the GPU's share the frame buffer of 4GB? So it'd be 2GB each. So if I just got the 2GB models it'd be 1GB each. And wouldn't that sort of bottleneck them in games if they only had 1GB each? Thanks in advance if I don't reply to your answers
