I made the switch to 645DF with a P45+ a year ago. I went for 28, 80 and 150mm but added the 45mm quickly. DOF is an issue for many landscape shots (particularly with 80mm and 150mm lenses) compared to FF DSLR and would recommend getting Helicon focus.
View camera wise, the cost mounts, but I used a Linhof Techno for a week and would like to add one when funding permits. Having used 5x4 previously, the absence of tilt in particular and front rise/drop to a lesser extent is something I miss.
Computer wise, my 4 year old 2.16GHZ MacBook Pro handles the files ok, but struggles, the 120GB HD means that I have to delete files once back from a trip ready for the next. My Mac Pro is from early 2008 and has only really grumbled when trying to stitch a panorama of 14 vertical frames.
Obviously your P65+ files are that bit bigger, so interpolate from my findings.
