I had thought to use PAE patch for RAM
Yep , but that would be "fun" .
The whole point that a lot of people misses IMHO is that there is EITHER a *need* for more than 4 Gb of Ram (or 3.85 or whatever the 32 bit OS will be able to actually accesss) OR there is not this *need*.
Any and all "normal" activities on a PC can be carried within the 3.x Gb of RAM, and this does mean "any and all normal activities".
Then, if you use a lot of high end, professional or semi-professional software and ONLY IF you use those, like as an example software for graphic processing or photos, or you do video editing or CAD/CAM (and rendering) or, say, forensics to name a few, THEN the 4 Gb starts representing a real world limitation, BUT what you really need apart the larger amount of RAM is an absolute (or at least very, very high) stability of the OS, you don't want to have a crash when 3/4th into a rendering session or halfway through a video animation.
You do not really *need* to have 231 sessions of Chrome open , rarely a Word or Excel document exceeds 5 Mb (megabytes, not gigabytes) in size, etc., and IF you need to have that then you need a stable system.
