xdon82, in a practical sense, you only need as much memory as the software you are running requires. 8GB of RAM can completely fit all the software 99% of us need to have loaded in memory. So you can run without VM / pagefile / hiberfil.sys for RAM sizes 8GB and larger with Windows 8/8.1 and before.
For kernel debugging / dumps, you want to have 200mb-800mb pagefile, and some software requires a pagefile - unnecessarily - but it is a historical anomaly - if after turning off pagefile - set to None or 0 - a program complains when you start it, enable 200MB and go up from there as needed. If you enable too much VM pagefile then Windows will start to use it as backing store - unneeded disk IO ensues.
If you actually need VM pagefile because you need more memory than RAM available, you are already screwed - as performance will drop like a rock - you need to buy more RAM, not enable a large VM pagefile 🙂
I have been running Windows / Linux / Solaris / etc without a pagefile for better performance for many years... successfully 🙂
Disabling hibernation will also save you space on the C drive, which on SSD's is at a premium. I have saved 64GB on my C drive because I have 32GB of memory the System pagefile/hiberfil.sys were 32GB each. With 8GB you are saving 16GB on your C drive.
Here is how to turn off pagefile, and hibernation:

I wanted to disable virtual memory because I have installed 8GB fast RAM. but when I did it, I used to get information that I had inssuficent memory, even if there was still 40% available free memory. Sorry for my english 😉 please correct my sentence [syntax]
When I set windows to manage it - I saw 8gb virtual memory for 8gb physical mem - I did not get it - it was strange . why so large pagefile ?
Now I have set manually 512-1024MB and it seems ok..but I don't know. I completely do not understand why I get errors when I disable virtual mem while is not fully used

I have 3 computers with 8GB RAM, 2x Windows 7 and Windows 8.1 on my G56 - the same problem on all - 8GB is not enough when disabled virtual mem 🙂
