|Okay, one more question. Are there any huge advantage or something that would amaze us about having "64bit"?
1. Better memory management. Because it is a 64-bit system, the OS can allocate larger blocks of memory to programs, and be more effieicnt at the same time.
2. Performance. Even 32-bit applications can get a performance boost from upgrading to XP64. On my machine, I have already installed Photoshop CS, Macromedia Studio MX 2004, World of Warcraft, Splinter Cell: Chaos Theory, and COH: Pacific Assault. Every one of these programs are more responsive and run noticeably smoother than they did on XP SP2. Photoshop filters run almost twice as fast as they did under SP2, Macromedia loads in a flash, and even WoW, which I always had problems with when entering larger cities, runs butter-smooth now.
3. Drivers. So far, the only driver I haven't been able to find is the modem driver. All other drivers were either included with the OS or were available as a download (the Catalyst 64-bit official release and the Creative Audigy 2 drivers were the only ones I had to download). Out of the box, I got 1024x768 resolution, which wasn't too bad, except that I prefer to run mine at 1200x800 all the time.
4 Compatibility. Most programs are compatible with the 64-bit version, with the exception of several AV & Firewall programs (you can install Avast for AV and Tiny Firewall 64 to address those needs). I know many people like the Windows Firewall, but I prefer to have more control over the program than M$ wants me to have.
5. Other. I have noticed that the wireless connection connects almost instantly under XP 64, whereas I'd often have to wait 30 seconds or more under SP2. Even if the connection drops for some reason, it usually reconnects even before I notice it. This makes online games such as WoW less susceptible to timeouts. I have also noticed that the system as a whole is more responsive, which is a timesaver for many of the tasks I do on a regular basis. All in all, I'd recommend upgrading to XP 64, because the overall performance, responsiveness, and compatibility is far beyond what was available for XP when it was first released.
