If your /home is separate you can upgrade without loosing your user files and settings. But 32 > 64 requires a new install

you can still install 64-bit softwares without reinstalling your OS

As the other thread says: "64-bit only comes into play with over 3 gig of ram. "

And slowness is not caused by having more than 3GB RAM. So I think going from 32-bit to 64-bit won't solve your slowness.

Maybe you should give the specs of your system: CPU and RAM.

This is a general misconception -- that 64-bit OSs run faster than 32-bit OSs.

They don't.

I know that for a fact because I did some testing, both of Linux OSs, and of Win7, on a PC using both 32-bit versions and 64-bit versions. And in no case, did the 64-bit version run faster.

You often see faster results reported in reviews because they load down the PCs with at least 8GB of memory. Since 32-bit can't even use all of 4GB, the extra memory improves the real-time performance of the PC.

But, it your PC is running slowly in 32-bit, changing it to 64-bit will not get it to run any faster.

When I updated to a 64-bit on my computer with 4GB ram, I did notice a few things run slightly faster. However, when I had a friend come over to download pictures from his camera to his USB key that ran very fast: about 20 minutes for 400 pictures to download. If you use something that takes up a lot of CPU, then you will notice a big difference.
