Just buy the base and then buy the M3 Max.Mac Pro 12 x 3.46GHz 48GB Ram, Sapphire 580 RX 8GB, 256GB NVMe drive, all SSDs. Used mainly for audio/music/recording, as well as FCPX and Capture one.
Wondering if the base model with 32GB will be enough... really want the Ultra, but £4k is just a bit much for me, I think. I won't be buying from the Apple store so leave it a week (or 4) to see it in stores/on Amazon.
