Graphics card for old laptop (Dell Latitude D620)
I want to be able to play the Sims 3 and Secret World, but my computer is really old. I can't afford a new one for a while, but I do have a couple hundred I can spend to try and make it run games half-way decent. I have a friend who knows how to upgrade them if I get the parts. It's a Dell Latitude D620, and I have 2 GB RAM, which I believe I can upgrade to 3.5 RAM.
I'm also looking into a new graphics card. The intel one it has is crap. What kind of graphics card would work for this model? Also, how can I improve the GHz?
