Well after doing some more checking, I was incorrect. The ram in my PC is a set of teamgroup and is running in dual channel, verified by cpu z. I guess what was throwing me is in the bios this ram didn't have an xmp profile available. Oh well whatever. It's happy. So I'll probably toss in an i7 and call the pc good for a while.
I'll think some more on what to upgrade my wife's system to. I'm thinking a pink case of some kind.
Lian Li has the LanCool case in pink, 205 or something like that. I did a build in a black one and it is a really decent case for the money. I got the one with the ARGB fans and pretty sure it was ~$70. I was going to do pink but the wife asked me not to unless I could find purple. So black it was.
