I'm building a new box , based on an Asus M2A-VM mobo (old , but
I'm familiar with it , already have 2 in use) and a quad-core AMD

probably Ubuntu 16-04 . I'm wondering if the Ubuntu has the same
limitation of 3Gb usable RAM that 32 bit versions of Windows has .
Anybody know ?

i'm not aware of any limitations like that, is it
a problem with the motherboard?

No , it's a limitation of Windows XP 32 bit OS's - I'm not sure if this
limitation applies to other versions of Windows . It will only recognize 3
Gb of RAM , the 64 bit version will recognize up to (I think) 8 Gb . The
"new" motherboard came with 4 Gb installed , along with an Athlon X2
processor (speed unknown) which will be banked as a spare . My plan is to
install that quad core and bump it to 8 Gb of RAM , see if I can get better
performance than this desktop .

It is a limitation of 32 bits, applies more or less equally to any OS.
