Thanks for that info.

I had a suspicion that the GPU could be a sticking point.

I'm trying to price it up with all-new components so that someone can 'follow 
in my footsteps' (or not if it comes to nowt)

Obviously, the Ti4xxx series is no longer available 'off the shelf' and their 
equivalent is that FX5600 / FX5700 series. - I only just noticed that the 
5200's have roughly half the transistor count of the Ti4xxx / FX56/5700s :-O

The FX53,5500s are the same deal with only 45mil transistors :-/

So I'm either going to need to get lucky with the suppliers or the price must 
go up.

There is always NVCLOCK http://www.linuxhardware.org/nvclock/ but that usually 
leads to 'molten-gpu-syndrome' ;-)

The goal of this idea is a projected panorama system (min 3 screens) and then 
possibly a modular cockpit system (convertible from an SEP all the way to a 
Multi / Jet).

For projection, I'm looking at building projectors myself. This will be my 
third design; I've already constructed an OHP based one and a higher-quality 
linear projector.

I hope to be using cold LED illumination. - Suprisingly, LED lightsources are 
now feasable as there are 1-Watt(!) white LEDs with built-in collimators on 
the market. You would, of course, require several banks of these. Soon, there 
will be 5-Watt(!!) LEDs on the market of the same design. For 'enclosed' or 
semi-darkroom projection, this is ample.

Here is an example of a compact 'cold' projector using 1-Watt collimator LEDs:
