Buy more memory. If you can, buy a larger computer.

A file that large is about 230 MB in RGB, or about 306 MB in CMYK. That's not
unreasonably large; I work with files that large or larger on a regular basis.

I have manipulated files well over 400 MB in size on a several-generations-old,
400MHz G3 system without difficulty. However, that system has 640 MB of RAM,
and would be better off with more still. If you intend to work on files in the
200-400 MB range, it is absolutely essential that your computer have sufficient
RAM--it's the single best investment you can make in Photoshop speed.

Could you make it 40 x 25 and enlarge when complete?

Sorry - just noticed the bit about "loss in definition" you would obviously
get some of that!!!

I am a bit surprised. Wouldn't that be the time to recommend doing the
illustration vector based? The size given together with the pixel
numbers show a 72dpi image which leads to certain ideas about the
process going on here....

I agree with Xalinai but it cold depend on what he is trying to do,
maybe a combination of Photoshop with Illustrator and/or InDesign.
