Just acquired a Dell Dimension 3100 off my girlfriend and its a few years old and i really want to get it to be able to play games like Skyrim, Call of Duty etc but i NEED to update my graphics card. All i know is that i need the following;
- PCIe 1.0/2.0 as 2.0 is backwards compatible
- x1 BUS Interface
- Maybe DDR2 (Not quite sure)
But even with that you are going to have problems in modern games, as the CPU is going to hold you back hard.
What kind of CPU do you have? The spec sheet does not really specify.
EDIT: It seems as if you dont have a PCI-E X16, so you are not going to be able to upgrade the graphics card. There are PCI-E X1 cards out there, but there is no way they are going to be able to game at all.
Your PC does have PCI though, and this card is the fastest that runs with a PCI interface:
