I have a 5/10 Mhz XT clone with a 28 ms 80 meg scsi and 1 360 k drive. I am
 thinking about upgrading by purchasing the Intel Inboard 386/PC w/2 meg 
piggyback. Would I need to upgrade my 100 W power suply (moniter plugs in wall)?
Are the increases in efficiency worth the $460 price tag? What are the
increases in efficiency? I know it disables the ram on the cpu, so does
the bios also become disabled? 

I use Tubo C ++ Professional, and just received my first big project.
I need the memory and spped now but I don't receive the money until the
project is finished (~8 months), so I dont have $3000 to sink into a 
new system. I'm just looking for quick fix and don't need alot of
"Just buy a 386" because , like I said, I don't have $3000.

Thank you.
