I am currently running a core 2 duo E6600 on a ASUS P5NSLI Mobo. My OS is XP 32. I am considering upgrading to win 7 64. I am going to buy a new hard drive and make that my C: drive. My question is, does anyone know if the P5N SLI Mobo will support 64bit ops? I have looked on the manufacturers site on it and it does not say either way. In other words, I am ignorant of the ways of mobos and 32/64 bit requirements. I do not have a lot of cash to drop this year and am looking to see if this is a viable option.
