The reason why I am getting windows 7 32 bit is because I am building a gaming computer and I have a lot of old games I still like to play and I don't want to deal with driver issues and on any of my adobe programs, etc.
You need to do some more research, as you have a few wrong ideas about running a 64 bit OS.
While you MIGHT have some problems with very old games, it will not be because the OS is 64 bit.
If a game will not run on Windows 7 64 bit, it very likely won't run on Windows 7 32 bit either. It will be a Windows issue,
but not for the reasons you are thinking.
"Programs" written for 32 bit code will run perfectly fine on a 64 bit OS.
The problem you might have is with certain older hardware and drivers, but.....
Driver issues will NOT be a problem if you are building a new computer, using new hardware.
Anything "Adobe" will work perfectly fine on a 64 bit OS.
Adobe's programs, like most design and graphic programs, have been running on 64 bit OS's for a over a decade.
Today, if you are going to spend money on a new OS, you would be foolish not to buy 64 bit.
If you use Adobe products, I would think that breaking the 4 gig memory barrier of a 32 bit OS would be a desired benefit.
Remember, it's not application programs that have a problem with 64 bit, it is hardware their drivers that were written for
32 bit that have a problem with a 64 bit OS. And, as I said, if unless you are going to be using some very dated hardware,
you don't have to worry about that either. Probably the worst thing people have problems with is peripherials, like old printers,
scanners, etc. These are the kind of things you have to look at, if you have them, and see if there are 64 bit drivers available.
To that end, if there are Windows 7 32 bit drivers available, they will have Windows 7 64 bit drivers available as well.
So take a good long study before you buy Windows 7 32 bit instead of 64.
And yes, latencies are important. More important than most of the time than bus speed.
You will notice a speed difference more in memory latencies of say....9 to 7, than you will a bus speed difference of say...1333 to 1600.
