Apologies if this has been mentioned before (I did search and I was surprised I didn't find anything). Anyway, the question is what operating system do people consider best for gaming? Should I be sticking with the old school XP 32-bit with 3GB RAM or going for 64-bit Vista with 8GB RAM?
BTW - this is for a new rig some HW specs are yet to be decided although I am looking at something like 4GB. QuadCore, HD 4850 512MB.
I am in a fortune position to have a MSDN license so potentially any version of Windows is available to me!
Thanks for your opinions, they will be gratefully received.
