Okay so I got my Arch gaming setup running at a basic level, don't think sound works I havent checked yet and I need to still add tweaks in for the kernel but there is one major problem to this system, Steam crashes X server every time I attempt to launch it, then returns to the login manager
Ideas what cause this, I am using the AMD open source driver.
Steam ships with some packages that are targeted towards ubuntu, so they're outdated and conflicts with newer ones that Arch uses. Removing libgcc_s.so.1 and libstdc++.so.6 will most likely solve your problem.
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/lib/x86_64-linux-gnu/libgcc_s.so.1
rm ~/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/usr/lib/x86_64-linux-gnu/libstdc++.so.6
