I'm running Xp Prof 32 bit. I have 2GB (2x1Gb) sticks of Corsair XMS2 DDR2-6400C4 CAS4. My mobo is a Gigabyte GA-M59 SLI5 which has a max capacity of 16GB RAM. I know Windows XP 32bit only recognizes 4GB memory max. Does it make sense to get more memory, either another gig or a full 2 gig (assuming I will eventually upgrade to Vista may later this year? Granted, I am running an Athlon X24600 and am also considering getting a new board and proc (intel) but that would be more expensive than getting another gig of RAm if it'll help boost performance. At this time, my system runs very well,so I'd rather not waste money on RAM if it's not going to be a huge deal. Thanks in advance.
