And what exactly is the downside to using a 64-bit version of Windows? There are few programs that do take advantage of it, but for those few programs there is a definite improvement. Office 2010 is also one of those programs, and it actually runs much better in 64-bit mode. The only advantage you gain from using 32-bit Windows is the ability to run 16-bit software, which is completely useless for the vast majority of people (and can be done through virtual machines running under a 64-bit host OS if it's really necessary). Vista and Windows 7 serial numbers work with both 32 and 64-bit versions, so there's no extra financial investment either.Its threads like this that have really kept me quiet around because to many people are pushing stuff and talking more out their ass than anything.
People have been saying "64bit is the way to go" since Windows XP x64 came out and how far in progress have we really made? Very little.
Very few games support more than 1 processor let alone 2 and most applications aside from a few rare take advantage of 2 let alone 4.
Most software is also written in 32bit code so it doesn't take any advantage of 64bit or extra memory you have.
The only thing running a 64bit OS is gonna do for you is allow you to see 8gb of memory instead of 4gb of memory.
And just because 8gb of memory is so cheap doesn't mean its needed.
