I have 4gb on my Vista 64 machine. So far upon boot up its around 36-38 percent used. I have different desktop customizations. If they are all running I believe it goes up to like 50 percent or so. I understand that Vista already uses a good chuck of RAM and my computer is not slow at all. (Waiting for Windows 7 later this year) I was wondering if it would be wise to just get 8gb. I see it as an advantage to have multiple programs running and only the processor maybe lagging. I know that more than 4 is not really used because of the way my E8500 Core 2 Duo uses it compared to the new I7s that uses ddr3 and takes advantage of having more ram. Just wanted some thoughts. If you need to know the PSU wattage and what I have in the computer so far to make sure there is enough power just reply. Thanks for your time everyone.


















, And my cpu is 32/64bit so doesn't matter here.
