new old design PC motherboard suitable for mach3?

Long story short is like this..

My old shed computer was failing, random crashes.. I replaced the RAM, graphics card, no changes, then it died..

I purchased a new socket 775 motherboard on ebay as that was the likely culprit...

I get it today and install the CPU and no POST, no beep....

Upon doing some research the motherboard I bought does not support my CPU (intel E8400).. The motherboard only supports up the processors the generation before mine (about a 6600 is about the fastest it will support) even though the socket is the same..

Now the motherboard has a parallel port as standard.... I do not yet have anything to do with CNC but I remember reading with MACH3 you use a parallel port..

So would this motherboard be any use as a MACH3 controller? It has integrated graphics as well, and the DDR2 RAM I have is only a few months old and is the small form factor..

Yes. I have Mach 3 running under Windows Vista on an old (Core 2 Duo, about E6400 from memory) machine, so you don't need to stick to XP, either.
