RESOLVED: am thinking of getting this PC, for both gaming and developing

Edit: This has been resolved. I now have a new computer, built from parts, described in the post reply #23. Thanks again for the help from everyone!

Any warning flags that more savvy of you have spotted?
Or is this decent upgrade from what I have for the $$?

I like that it is running lots of cores, and has room for upgrades (to 16MB). I’m guessing I’ll have headaches moving my older software over, but if nothing else, there are probably 32-bit emulators in existence. Will have to upgrade the software piecemeal.

My current PC is XP and very obsolete. Budget is very tight.
