Intel Quad q6600, 32 bit or 64 bit vista?

I recently upgraded my rig as follows

Intel Quad-Core Q6600
ATI Radeon 2900 XT 512mg
ASUS P5K AiLifestyle Series iP35 Socket 775
Windows Vista Home Premium 32 bit

From the qustion title my question is kind of obvious but il ask anyway.

Currently im using a 32 bit eddition of Windows Vista and have been told i can upgrade to 64 bit for very little money, I was wondering with my CPU being fairly new and being able to run games such as Crysis and so on if i would benefit further if i was to upgrade to 64 bit?

Im sure it would increase my performance on some levels but i have heard that it is not as stable as standard 32 bit, so what you think?

Also i want to upgrade to 4gb of ram, but have been told that with 32 bit that it wont be used to its full potential, is this true?

32-bit OS can not utilize 4 GB of RAM. 64 bit OS would be better choice under one condition: you have 64-bit drivers for all devices.

While a 64-bit OS sounds good in theory, with access to more than 4GB of RAM, the lack of stable drivers is the sticking point, in addition to lack of applications that will make use of 64-bit addressing.  If you are using this machine for gaming, it is better to stick with 32-bits until there is more support for 64-bits.  Games have not been written to take advantage of it yet.

All technical info from toniur and Callandor are true. Trying to gather the 64bit version of drivers (that works) for all your devices is very likely to make your life miserable.

My stright forward answer to your question is : Unless you like/love to experiment with 64bit OS for the fun or experience of it, otherwise upgrade to 64bit OS if and only if your need to run software application(s) that requires 64bit OS or requires more than 3.2GB of system RAM. Having a processor that can support 64bit OS does not mean it is better to go with 64bit OS.

Enjoy your Q6600~!

Thanks for the help
I probably wont be going with 64 then
If i do purchanse another 2gb of RAM how much will that show as 3.2? will it only use 3.2? or just show up as 3.2?
Toni UranjekConsultant/TrainerCommented:
It will show and use somewhere between 3,25 and a couple megabytes more, unfortunately.

Another suggest could be to dual boot the 2 OS's if you have the setup discs for both.
