I never really understood this problem, not since the days of sdr. Single
channel ddr3-1066 provides roughly 8 times the raw bandwidth of what a
2560x1440 resolution (at 32bpp, 60hz) needs so that should be plenty to serve
other MC clients as well (with lesser priority). So what's the problem there,
too small buffer size for scanout?
