I've recently purchased the sims 3 game and was extremely dissapointed when i could not play since my Dell "dimension 3100" did not have a "128MB video card with support for pixel shader 2.0". I enquired at the local computer store who said that it is not possible for an upgraded video/graphics card to be installed into my computer.. I also have a laptop which is a dell too.. Is it possible to upgrade this if not the computer?

I have heard about the "XFX GeForce Fx5200 256MB DDR PCI DVI-I VO" video card, do you know if this is compatible?

 Thankyou in advance for any comments..
