I was thinking about this the other night and wanted to see if anyone else has any thoughts about it. It seems to me like the larger sized MOBOs may soon become obsolete, along with larger case sizes. I started thinking about this last night while reading about the new RTX 3000 series GPUs. I am thinking about upgrading to a 3080 when they release (depending on the benchmarks) but then I considered adding a second 2080 to my rig, my PSU will support it. However, after reading about NVLink/SLI support it really seems like multi GPU setups are very quickly becoming obsolete. As soon as there is no more support for multi GPUs, what will the purpose of an ATX motherboard be? I mean seriously, how many people use PCIe peripherals anymore? I remember the days when I had PCIe wifi adapters, cable adapters, etc, etc. But now with USB 3.0/3.1, who really buys PCIe add-on cards anymore? It just seems to me like the need for multiple PCIe slots is slowly being phased out, just like disc drives were. I'm already at the point where I'm 90% sure that my next new build is going to be mATX or possibly ITX. What do you think?
