I'm soon going to start building a new PC and I want to know whether to go for the 32 or 64bit version of Vista. I want to put 4 gigs of RAM in the system but I heard that 32bit OS'es can only pick up 3gb. On the other hand I heard that the 64bit has some trouble with drivers? I want it to be as future proof as possible so some advice would be appreciated.
Thanks

32-bit Windows will only see 4Gb or not even that much. Driver support is huge and Vista probably knows what to do with the bulk of it anyway.
64-bit Windows can, depending on which version you go for, can see up to 128Gb of memory. Driver support is patchy and occasionally non-existent.

Do you really need more then 3 gig to run Vista properly?

As long as you've got quality RAM running at good speeds/latencies, then 3GB should well and truly be more than enough. It does depend on what you use your computer for, though...

Isn't it also true that most games or apps can not run 64 bit or run with errors?

Not strictly true though some (perhaps the vast majority) of legacy software will have issues under 64-bit Windows.
In the future though, all current software of the time would work under 64-bit Windows. When we eventually pass to a point where a need for 128-bit Windows would be needed, again 64-bit software would probably not work on it.
