I'm considering to install windows 7 64-bit, because of memory size, I know 32-bit version can not work with this memory size,
Therefore I want to know what your recommendation on this subject, in which PC I can install the windows 7 64-bit that will work smoothly with no problems?

Thanks.

You should run this application on both PCs:

Windows 7 Upgrade Advisor - Download - Microsoft Windows

You appear to be misinformed. Windows 32-bit will work fine with 4 GB of memory. It just won't be able to use all of that 4 GB--only about 3.3 GB.

I think those 2 CPUs are quite close to each other in an overall benchmark.

On glance i would chose the second one however stick with ignatzatsonic advice and use the upgrade adviser.

I would go with the Athlon 64 3500+ and do a "safe" overclock - should do around 2.6GHz with a Manchester core and if the mobo allows it. The 4GB of RAM will be just fine. The XPRESS X200 is about the same as the NVidia FX5200 so no benefit swapping it out.

My "old games" box / Linux test box has a 3500+ on a Gigabyte board running at 2.66GHz, rock stable.
