I am thinking of buying a new motherboard, Intel P35 chipset, and an Intel Q6600 quad core cpu.
I wonder: do i need win server to run all 4 cores?
i heard xp stops at 2?
anybody any experiences, as to which version i would need?
XP will detect and run a max of 2 seperate cpus. (1 cpu each in 2 sockets)
XP will detect and use as many cores that are available on 1 cpu in 1 socket.
So in short, yes you can run a Quad Core CPU with XP, and it will use all 4 cores.
