Future proof gaming PC (Win8), how much RAM is needed?

I'd like to get a new monster PC to play all PS4 and Xbox One ports. I also plan on getting a Samsung Evo SSD and use 1 GB of RAM to speed it up (it's a feature in the Samsung software). Also I'd like to disable the Windows pagefile and never get an out of memory error.

Seeing as the Steambox prototypes have 16GB of RAM, I'm thinking that could be the right amount. However, most PS3 ports require 2GB of RAM (4x the amount of RAM of the PS3), and I remember PS2 ports also required at least 4x more RAM on PC. PS4 has 8GB of RAM, so would 16GB or 32GB be the right amount? I know current games don't use more than 4GB, but I want the PC to be future proof for 5-6 years :)

Please advise!

(I plan to game at 1080p with a Core i7 4770K and an AMD 290 videocard with 4GB RAM)

Hi,
At this current stage as you said, 8 GB is more than enough for any game at the moment. 8GB of RAM is still a pretty huge amount of ram and that kind of amount will still last for a very long time if we think about gaming today and in the future.
However, if you'd like to be absolutely sure, I would recommend going with either 12-16GB of RAM. Unless you're going to do heavy video-editing, 32GB is a bit of a waste.
Based on this, I'd say you're fine with 12GB RAM for a long time. If however, you'd like to spend more money, get 16GB of Ram.
Since you're using Intel, i'd recommend picking either 1600 mhz or 1866 mhz sticks. I would personally prefer G.Skill Ripjaws X or Corsair Vengeance RAM sticks.
Hope this helps^^

Yes it helps, thanks! Just to be sure I'd stick with 16GB then :) Why would you prefer Rippjaws X or Corsair Vengeance? I was looking at this Patriot set: http://www.patriotmemory.com/product/detail.jsp?prodline=5&catid=34&prodgroupid=232&id=1259 (16GB, 2133Mhz @ 1.5V). The 2133Mhz RAM because the Xbox One also uses that. Can you tell me what is the best speed (1600/1866/2133) and why? I don't want the RAM to use more than 1.5V though.

(near the end of the lifespan I might overclock the i7 4770K or put in a stronger videocard or an extra 290 in crossfire)

Hey,

Corsair and Ripjaws are just personal preferences of my own. Patriot sticks are extremely good aswell and those go to a bit higher end than let's say ripjaws series.
As to regarding the speed, 1600 mhz and 2133 mhz do not have a large difference.
http://www.anandtech.com/show/6372/memory-performance-16gb-ddr31333-to-ddr32400-on-ivy-bridge-igp-with-gskill
The column is quite hard of a read and exhausting aswell so I'll put it to a nuttshell to the best of my ability:
AMD processors prefer more higher memory speeds due to their native 1866 mhz ram.
Intel has a native memory speed of 1600 mhz at current gen processors (i5-4670, i7-4770k for example).
If we compare a 1333 mhz and a 2133 mhz stick we might see a little difference in terms of gaming, but otherwise the difference is almost nowhere to be seen.
Memory is a bit gimmicky thing and I'm not an expert on it but personally, I believe that 1600 mhz ram is actually beter in some cases than 2133 mhz.
If you'd like, go to youtube and search for LinusTechTips (I think it was called). He did a video about the memory subject sometime ago and explained it a bit beter than I can.
I hope this helps a bit^^

Thanks again for the reply, it helps a lot! I've read the Anandtech article and the bonus of 2133Mhz RAM seems to be very little indeed. I wondered if you can overclock the processor without overclocking the RAM or the voltage of the RAM? <-- total overclocking noobie here ^^

Haswell likes fast DRAM:

16GB would be the way to go when looking back at all over the last couple years I clearly remember when folks said 2GB is all you'll ever need, a year and ahalf or so ago 4GB was being said to be more than you'll ever use, then and now many are saying 8GB is more than you'll ever use - it's never ending DRAM use increases on almost a yearly basis, a good indicator is to go to a store and see what's in the bulk of the pre-built computers - what ever that is - if building and looking to the future (even a year or so) you'll want more than the prebuilts come with - which right now is on average 6-8 GB

Thanks for your answer! I'm thinking now more of 1866Mhz C9 RAM (or maybe else the Patriot 2133Mhz C11 RAM as it's quite cheap over here). Happy new year as well :)
