The difference with a page file and temp folder is that the page file is used in place of having physical ram for computational stuff, temp files is used by programs for tempory storage (e.g running program installations, zip file extraction, caching files, etc). Turning off the page file just means the system will not try to reserve physical ram by pretending the disk is physical memory, it will still use temporary files though.
I'm using the program I linked to earlier, it's free for ramdrives up to 4Gb big, any larger and they ask you to purchase (it's cheap though):
http://memory.dataram.com/products-and-services/software/ramdiskIt does do restoring the ramdrive on reboots, I tested it before swapping all my temp folders over just in case
I've repointed my Temporary Internet Files folder to it, my Firefox temp files, my Photoshop scratch disk, WinRAR temp, and the windows 'common' temporary folders C:\windows\temp and C:\users\username\Appdata\local\Temp (which most other programs use for temp files)
I'm not sure what else I could point through it but that 2Gb fills quite quickly once I start using Photoshop. It's using between 200-500Mb right now just browsing and with Photoshop closed.
I will probably write up a guide on seting it up this weekend.
Bear in mind I have no idea how games will respond to this yet, I don't know how much they rely on temporary file space. I'm guessing very little though, swap file/physical ram is more the issue there I think.
