Just 6 months ago I installed windows 7 x64 from a x32 key. This is because Microcenter gave me the wrong disk. This was from a system builder key that had never been used. But, I have also been able to install windows 7 x64 from a OEM x32 bit key as well. I did this because I had an HP laptop that needed more RAM and 32 bit was holding me back. I have also been able to swap motherboards and re-activate a system builder win 7 x64 installation without even having to call microsoft. It just activated. I'm 99% sure whatever you want to do with your system builder license, you'll be able to do and if you're just replacing the motherboard, then I'll bet they don't even have you call the activation #. You'll just need to get a x64 disk and use the x32 key.
Here's my advice:
4GB sticks of DDR2 ram is expensive so you'll need to get a new motherboard. But, AM3+ is a perfectly acceptable platform to build on today. Not only will your current CPU be fast enough for her today, but in 5 years when she needs an upgrade you'll be able to drop in a steamroller CPU into that socket.
760G is a basic GPU that lacks video acceleration. With your X4 CPU, that isn't that big of a deal since the CPU is fast enough to render the video. The MSI board linked above is a solid choice and gets you video acceleration, but I think you will want to get a board with 4 memory slots especially considering your wife's usage patterns. This gigabyte is well rated on Newegg, is on sale, and has 4 slots. http://www.newegg.com/Product/Produc...82E16813128565
If you have enough RAM and windows x64 an SSD is not required but would be very nice.
Just getting an SSD wouldn't fix the problem which is the lack of ram.
