Hello - I just went ahead and put on Vista 64 Bit OS on my PC (I was using Vista 32) because I have 4 gigs of ram and wanted full use of all of them. I run a lot of memory intensive apps, so this move made sense for me. So, I'm just wondering if any other Vista 64 bitters out there have some tips, software suggestions, etc to pass along so I can make sure I get the most out of my OS. I was thinking about trying Firefox 64bit (minefield), not sure its ready to play with yet tho... Thanks for any tips or software suggestions your willing to give!
