Hey everyone,
I have  Processor: AMD Athlon(tm) X2 Dual-Core QL-65 (2 CPUs), ~2.1GHz
             Memory: 4096MB RAM
It says it's only using 2.87GB of available 4GB of RAM, and if I upgrade to 64-bit it will use all 4GB.
I'm just wondering if there are any specific disadvantages with using 64-bit instead of normal 32-bit.
Will it affect my computers performance, will I have problems with programs not being compatible, is there any point in actually upgrading to 64-bit? 
 Much appreciated.

I do not know a lot of pros and cons but here's the few i do know about.

Basically you get to use all ram and it's not that limited so if you wanted you could bump the ram to whatever your mobo can handle (or your budget).

The only downside that i'm aware of is that a lot of programs do not have 64 bit support in facct i recently had one where IE was telling me it couldn't do whatever it was at the time and to use it's 32bit browser.

But sooner or later you would like to think with the advent of multicore processors on the increase that 64bit will be the norm where 32bit may become the less common of the two. In saying that of course netbooks may stop that from happening.

If you dont run old stuff, then its a no brainer to go 64 bit.

Some old software has issues, particularly cracks for old stuff.

I switched to win 7 64bit this year from vista 32bit. Haven't had any major problems. I've only run into only a handful problems with some old software that isn't supported anymore. You can use virtualization to solve these tho if it's a must piece of software

i've been running win7 64bit for ages. no problems here.  main issues is finding drivers for older equip.

internet explorer launches 32bit version by default,  most plugins wont work with 64bit.

office 2010 is better installed with 32bit version as the plugins and other integrated apps are mostly 32bit support only.

Having said that, you won't have any problem running most of modern programs on a 64 bit environment. I am using windows 64 bit since Vista and it's all working well...

You don't need your applications to be 64 bit, unless you are dealin with large amounts of data. But the 64 bit OS will allow you to use all the memory you put in your system, and perform a lot better because of that.

In order to go from 32bit to 64 bit you need to do a clean install, So an upgrade disc won't work when trying to go from 32 to 64,

You wont lose anything if you have enough space on your hard drive.
Insert your windows 7 disc and when you get to the page upgrade or custom install, click custom. windows will put all of your files in a folder called windows.old. Once you have moved all your user files ie pics, docs, music and so on, click start and type "disk in the search bar and run the disk cleanup. Tick old windows installations and it will erase the folder.

My configuration is

AMD Phenom II X4 810 @ 2.6 GHz
MSI 770-C45 M/B
500 GB HD

Windows 7 Professional x64

Been using it since the release date (about a year ago). Works absolutely fine. Great for gaming.
