(Since I have to lie down most of the time atm I have not much else to do.)
I read through almost all the topics and threads here in this section. That gave me quite a picture of the current standards and specs. Have been out of touch. And it helped me form some ideas. Some of you guys have very intensive knowledge. I am not going to select all the parts at this time because in half a year much changes.
Let's begin with some then.
Price range in the US will be up to 1'500.- I think. (In Switzerland it will likely amount to 2'000.- because everything is more expensive here.) Hope to stay a bit below that.
After that I don't want to do a complete overhaul for the following three years.
Sure some upgrades, though

Following that thought, I want to get a really good case, PSU (Seasonic) and motherboard.
HDD, SSD (if necessary?), DVD sturdy standard.
GPU... Will wait till the last minute and see what will be a good deal.
One monitor will have to suffice. 23" LED/LCD (that thread was interesting

I am curios about OLED. We'll see.
Since the game will be up and running before I have my rig together I hopefully will have more input concerning controls. Mouse/keyboard, stick/kb, mouse/stick/kb?
What I already put an eye on is the Asus P9X79 deluxe, socket 2011.
Hopefully, price for an Intel core i7 will drop till end of the year...
Yes, I admit it, I am still an Intel man. Sue me :-)
Had a nice stable, dependable and good Asus/Intel/Nvidia layout running, back then.
Will get 8 gig of RAM (2x4gig). Kingston is still good but I am open to suggestions.
Do you think that mobo/CPU setup a good starting point?
As for the GPU... After all the reading AMD comes out tops, I think.
I will have one GPU which should be enough. If it gets to me and I want to go multiple then I could with that board.
That's my starting point atm. I still have some more research to do, I know.
I am open to comments, opinions, advice. I am no professional.
Gee, never thought I would write that much in one go
