Within short I intend to buy me a new PC - it will consists of:
Windows 8, Intel i7-3770K, Z77 motherboard
16GB RAM (or maybe 32GB, am not sure)
* Easy to find out how much RAM you have on any Windows OS host of guest- - just go to e Control Panel --> System
Samsung 840 Pro SSD (or maybe 2, not sure, if 2x SSD - RAID or not, not sure)
Some HDDs in RAID,0.
* If you are setting up the system with tow disk of the same size (always best) RAID 0 will give you twice the amount of disk space - but if one disk fails you have lost everything. Extremely fast however.
RAID 1 is mirrored and, at l east theoretically, you can recover your data byreplacing the SSD, settling up RAID 1 again (and other steps). You may still lose data if you the middle of a write operation when the disk failed.
With everything - you must backup - an external drive!
1, What would be the best RAM settings?
(Currently, with 8GB, and 4-core CPU and no SSD I have allocated just 1GB and 1CPU)
* W it h8GB and 1 GB severed for each VM you probably could run 2-3 VM I'm guessing. Remember Windows 8 VM will need 2 GB to install and run (as well as at least 30 GB disk space) Depends on what programs you are running on the host,. Number of virtual CPU's is a matter of some difference on this forum - you will need to decide for yourself. Sometimes I use one - on larger VM's (like Servers or maybe Windows 8) I might use 2. I have seen a difference in pperformance with 2 CPU's o my AMD hex core.
2. Wonder where to put the pagefile.sys
* If its the host you are talking about - with 16GB of RAM you are pretty safe using no pagefile in my experience - you might use a small one if you want to look at a crash dump (good luck with deciphererinig that!!)
Regretfully 16GB will rapidly be to small to create a RAMDisk and run vm in RAMdisk
(if at all that would be possible)
* I have used a RAMdisk for a VM - it is certainly much faster for smaller VM's. However the speed increase varying the virtual OS. Since yo will need to copy the VM to your hard disk in order to save itl you will be much bettter off to use an SSD.
I may have confused host and guest in some of these answers - I'm not sure I completely understand which you are talking about (probably my mistake).
Good luck
