Can windows 32 and x64 share the same programs on diff partitions?

My friend just go this cool tv card and stuff for his pc, so he got windows media center 2005. he will sell me xp pro x64 for $25. i was going to buy that origonally but decided against it due to lack of driver support. Is it good enough now where i can install my games (cod2, bf2, flight sim 04, fear, etc.) and have them work and have all my hardware drivers? Or should i partition my 160 gig hard drive in half or thirds and have a partition for 32 and 64 or 32 and 64 and programs on their own? can this work? Like.. can I have one installation of something and have both o/s's use it. So like I dont have to install everythign twice (once for each o/s) Anybody that knwos anything about this please help as im very willing to spend 25 bucks on x64
 
I guess it depends on what settings each game keeps in the registry that wouldn't be accessible to the other operating system...in my experience, some games (like the Unreal and Unreal Tournament series) work just fine being copied over or run from a different location (not installed), but I don't have much experience with doing that with other games. The games themselves should work fine (ignoring the issue of reinstallation), and based on your sig, you should be fine for driver support in x64 (it's mainly people with "exotic" devices such as TV/HDTV tuners who are screwed for x64 support...).

Oh, and do NOT install x64 to the same partition where your regular XP installation is. I learned that one the hard way. 😛
 
Do I have to get x64 drivers for all my hardware (like mobo) before I install? Or should I partition in half, install xp pro 32 then install xp pro 64 on partition 2 and then....? I just want to know how if I can run programs between them and how to do all that crap. But like as far as software goes... do I have to get special versions of software to install, or will regular 32 bit programs go onto x64?
 
i've got a question. does a xp64 give a majopr boost in performance or something. i mean is it really worth the trouble buyijg, installing, trouble shooting it.

by what ive heard, yes in some cases. Why else would hey build a 64 bit processor?

Generally it's snappier and there should be some performance boost, but probably nothing outrageous.

To get around the VM limits on the 32-bit processors. On a 32-bit processor each process is limited to 4G of VM, 2G of which is reserved for the kernel so each process can only address 2G of VM at most (ignoring the ugly hacks in PAE and AWE). Certain applications like databases, 3D renderers, etc can benefit greatly from the additional VM on a 64-bit machine. But most userland apps won't see any benefit from a pure 32-bit->64-bit conversion and some might even slow down.

The real speed benefits come from the better hardware, not the 64-bit'd-ness of the architecture. The extra GPRs (although a process has to be 64-bit to use these), on-die memory controller, more cache, etc are much more benefit to mainstream applications.
