The soon to be released Kingdom Come Deliverance wants 12GB RAM, Tangledeep only 2GB but is in spite of that 64bit only, Hellmut: The Badass From Hell wants 8GB RAM and Sherlock Holmes: The Devil's Daughter also wants 8GB. I just went through the latest releases/upcoming excluding DLCs.

What Mr Mumbles said. A lot of games nowadays are actually 64 Bit native. Also I always assume that getting a PC means not just gaming but also working with it - otherwise you could just get a console. And working with digital photographs or editing your full-HD or even 4K home videos will require lots of RAM, unless you want it painfully slow.

Also background processes, browser windows etc. can take up a lot of space too. Right now I'm using about 5.5 GB, meaning if I had 8 GB total, there would be only 2.5 left until the OS starts swapping. That's easily consumed even by a 32 Bit game.
Thanks for gathering that info :-)

Here is something more to think about if you want a new computer this year: Do NOT go for AMD's old APUs, you can cheap out and buy such a system used alright, if price is low enough, but not as new. The new upcoming APUs are much better and someone mentioned them already. APU = processor + powerful integrated graphics (typically equal to or a bit better than the lowest graphics cards of the latest generation.) Then you can add a graphics card a few years later when the intergrated is just too weak.

Preferrably not below four cores. Absolutely not below 8G RAM.

Computers are expensive :-( Windows 10 Home seems to cost at least 999kn, which I presume is your local currency. I guess that is for OEM version = locked to that computer hardware.

So on which console can you play Kings Quest III, Warcraft II, and The Witcher 3? How is keyboard & mouse control on most consoles? How do you play DOS/Windows-only games on consoles? Etc. Etc.

You can play Witcher 3 on XB1 and PS4...

To play KQ3 or WC2 you don't need a new PC at all. Some old second hand machine will be enough ;-)

Of course if you want to play games that are exclusive for a system - you have to get that system. In that regard a PC is the most expensive, but also most versatile system.

But the original discussion was 16 GB RAM (instead of 8) vs. SSD. Where I would prefer more RAM before an SSD if you can't have both. Because some things you may want to do (other than gaming) can use it, and also because there is an increasing number of games that require 8 GB (or even 12) as a mininum (as Themken pointed out).

I never had more than 8GB and did not experience any problems at all even with newer games. Most games want as much VRAM as possible but 8GB should be enough at least on non Win10 OS. Win10 as far as I am told does use a lot of RAM but I am not sure if this is the truth since I don't use it myself.
I doubt that many PC users are using their PC for photo editing or thingts like that. (but of course when you start to use such applications RAM will get much more important). I use my PC for browsing, watching videos/listening to music and gaming only and PC imo still is better than console so I would not say that people who only want to play should just get a console. Imo it's simply not an alternative for everybody - just think of those old games that won't run on any console at all ;)

PS3/4 ??
Except they too have also taken up some of the bad parts of pc gaming.

To what is this: "PS3/4" a reply? Does the Playstation 3/4 play King's Quest III or Warcraft II? Can you play The Witcher 3 on it with keyboard and mouse?

What are those "bad parts of pc gaming"?

You probably could and what's this obsession with the inferior control system of keyboard and mouse that isn't really needed for the witcher 3 anyway.

The bad parts are the DLC, always online, remote updating and other assorted nonsense.
It's bad enough on the PC that there's a good case for having a stripped down standardized PC gaming system to do away with most of it.

thanks for the answers, Themken, Toxic Tom but I remain unconvinced.

Those games you mention look as though they will play on w10 64 bit (recommended), but the specs also mention minimum system requirements of w7 and w8, and 64 bit is not specified against those systems.

Whilst I am not certain, I strongly suspect that there would not be a separate 32 and 64 bit game executable released for these titles, as these would be massively different beasts.

Rather, I would believe that the games you mention are only 32bit execs capable of running on 64 bit OS's.
