Pretty sure you meant-> diffrent between 32 bit os and 64 bit os..

The difference would be 32 bits

The biggest difference a typical user would notice/be able to use is that a 64 bit OS can use way more the 4 gigs of ram. 32 bit OS is limited to 4 gigs or ram but only uses about 3.2 gigs.

The actual limit for Windows XP is generally anywhere from 2.8 to 3.8 depending on a number of factors including software and hardware.

For server operating systems, you can get far more than 4 GB of RAM using AWE (address windowing extensions) which supports 36-bit memory addressing. Of course, applications have to be specifically coded to take advantage of this though! Exchange Server, SQL Server, Oracle, etc are coded to take advantage of it.

But as you said, nothing beats memory access than using a 64 bit CPU and a 64 bit OS.

Is it just in the OS that you notice the difference in the memory or in games aswell?

I dual boot with vista 64 and Xp 32 and i must say i really like vista 64 but theres not much advantage for gaming yet unless the games needs more than 4gb of ram. There aslo can be the odd driver issue and stuff but genrally my experience with vista 64 has been great. I use alot of fractal programs that are written for 64bit and they run great.

And to answer your question yes the game would be able to use the extra ram that was available to it, not that any games need that much ram at the min.

I built a new system back in February for my jump from XP to Vista. Wanted to future proof as best I could. Went with an Intel Quad Core and 4GB of ram. Decided to buy Vista Home Premium 64-bit from Newegg. The only driver issue I had was with my Dazzle USB video capture device. Replaced it with a Hauppague internal capture card. I also had to drop WebRoot's AntiSpyware/AntiVirus package because they didn't have a 64-bit version of their software. My yearly subscription was about to expire anyway, so I went with Kaspersky. The only adavantage I currently see is with my video editing and when I'm using my Adobe CS2 applications. I'm patiently waiting to see what happens on the game market. Was EXTREMELY pissed off when I found that EA Sports wasn't coming out with a 2009 version of Madden Football. Was hoping to put my DirectX 10 video card to the test. I feel that going to the 64-bit version of Vista was a good choice. No regrets.
