Ahh I see, np Rahja, probably better to keep other threads cleaned in some cases.
To Dilan, 2 gigs is plenty enough, I don't know if these apps would put that much of an FPS hit on Guild Wars since you have the RAM to back up the extra memory that they use. I could imagine dreamscene possibly putting an FPS hit on, since it is animated, other than that, you should be fine.
Also, not all of these programs are free, but a lot of them are, for example, Windows Blinds isn't free, but it is relatively worth paying for as it is a nice program. You can head on over to
www.stardock.com for some awesome mods, most of them come free / with the option to pay, but their free versions work awesome and don't have much limited functionalities.
EDIT: Btw everytime I get on Vent no one is on Rahja. :P
