Oh Righty, So by now I have totally re-build both my office and gaming pc's, since I received my latest GPU...
Man was I shocked at the size of this new GPU, 1st I thought it would never fit in my Coolermaster case, and that I'm going to be screwed until I either buy and additional case with new GPU dimensions in mind or make some sort of drastic swap of both my pc's cases, lucky I was and the other office pc had a NX 220 from Antec.
After I got out the tape measure and actually started checking possible restrictions did I find that my office pc box was going to be just right, so did I set forth and disassembled both pc's, first I re-build the office pc into the Coolermaster case, now that pc has the DVD drive still utilizable and I kept each motherboard's accompanying PSU with where it was before, I also swapped some of the PCI-E power plugs on my Antec PSU to some new ports just for some extra measure, since the new GPU was going to be using 3x 8 Pins.
At the point now that everything runs smooth, And I'm quite happy with my Re-builds, they are nice and clean and I'm proceeding downloading and installing games and software, Oh 23h2 for now, seems nice and stable, The mismatched ram isn't an issue at all seems like and I won't be requiring any ram at this point, end of the tale is that my previous GPU (RX vega 64) ran it's last game in my pc, good bye my lovely GPU, served me quite well for such a time, along with that I also found that the very old GPU that had been in the office pc was also busted, so now the office pc is running it's Intel HD530.
