Dell is absolute gar-bitch ;_; They charged me $80 for 512mb of RAM in 2005. Never buy from Dell, EVAR AGAYN!
Now, recently I altered my Dell by adding a new graphics card and a new power supply (to power the card)
I got this card -

Some Dell computers
may use special proprietary parts, so you have to buy special parts from Dell to upgrade your system. In my case I didn't need to buy anything from Dell, and both of those parts work fine for me.
