What CPU Should I Get for an Asus Crosshair IV Formula?

[IronOrchid]

So I'm a graphic designer student, and my laptop just lags too much running adobe programs, Photoshop and illustrator mainly. I was going to buy a desktop because I prefer to work on those anyways but a friend donated his gaming desktop to me. It's missing a CPU and GPU as far as I know, but I'm completely new to the interior structure of computers. I'm just googling everything as i go, trying to get this thing to run. The motherboard is an Asus Crosshair IV Formula. I know it has an am3 socket, so what would be the best CPU for this? Will it work with an am3+ or ADM? I am planning on doing some gaming (Fallout 4, No Man Sky, stuff like that) as well as running adobe programs. It came with 2 4gb RAM...sticks? Chips? Plugs? I don't know what they're called....

Also, what GPU would be best? I haven't really done any research on that yet since I'm trying to tackle one thing at a time since this is all new to me, but if you know off the top of your head that'd be great.
Thanks for any help in advance!

Sell that board and go with Intel. The AM3+ socket is old as dirt as far as PC components go. The best cpu you could get is the FX8320/8350/8370 and it would perform about like Intel i3 at overall.
