I agree. The superfetch feature just makes use of ram that would just sit there otherwise doing nothing. As long as the ram is available to be used when needed and does not result in additional swap file use then its OK.
That being said I would not bother going to 8Gb if you already have 4...a couple of apps MAY open faster (via superfetch) but that would probably be it. If you do go to 8Gb I certainly would not fill up all four ram slots.
Or out of the 8GB using 4GB as a RAM disk to render your authored DVD or transcoding, especially if you ahve 1 HDD, that would reduce wear on your HD and you would gain performance as you would avoid the constant back and forth read/writing/update fat cycles. No benefit to games otherwise, only 2GB at once can be accessed by a 32bit app so to be honest you don't need 8GB for gaming.
I had 8GB and I found I never got close to using all of it so I sold 4GB.
I run with no paging file but now, every once in a while, I'll get the low memory message (eg. Running Age of Conan, F@H, Firefox, MSN Messenger) but since I very rarely do that...it's not a big deal. And even then, it's still only using 80% of the RAM capacity or so.
So really, as has been mentioned, unless you really see a situation where you need it, 8GB is probably unneccessary.
Okay, Okay, lets get this all sorted out. First of all, the way microSHAFT uses ram is a total waste. This while 64 bit garbage from MS is that. garbage. TRU64?
AIX? those are real 64 bit. Not emulated, or attempted heheh. And the real address space from the begining is called an inode. Try some reading material to brush up on the history, but its better than valuim LoL. The design and implementaiton of the 4.4 BSD operating system. Complete freeBSD. Or even the TRU64 man pages if they are still posted online. THese were actually designed for serving really really large databases. NT code wasnt. NT servers were really designed to support business processing. THats why colleges like SAIT, NAIT and BCIT push NT,coz most business dont use octa processor servers laod balanced with itanuim back end databases. THats why hotmail used to be on freeBSD LoL MS couldnt manage ram on that scale. So, does vista use 8 GB, no, not unless the application does.
