I just today got my DIY PC amd phenom II x6 and 8 gigs of ram etc. I built it and formatted the solid state with windows 7 ultimate. I was wondering if I format with xp 64 bit will it utilize all 8 gigs of ram and possibly use less resources and further improve performance. I did build this PC mostly for gaming. Thanks in advance for any help.
XP 64 bit will use all 8 GBs of memory (as its x64 bit), when it needs to, otherwise it uses less then 1 GB of memory idle
XP x64 will also be a bit better for day-to-day usage, as it reduces processor & disk activity compared to Windows 7.
