XP could play 4 games at the same time on a Quad Core! Just kidding.
Some XP compatible games like Crysis can use resources from all available CPU cores. Multiple CPU cores can also off-load additional background tasks from the primary core.
I think the QX family uses a Socket 771 vice Socket 775. The Quad Core models for Socket 775 run at lower clock speeds stock compared to the Duo Core models (you could overclock them though). They also run with higher power consumption.
