Not sure if I should be posting this here or in the Gaming and Technology forum, but I've had good success here in the past so I figured I'd give it a shot.
The situation: My PC is a couple years old, and is starting to have serious problems handling games even on really low settings. My initial thought is that I need a new graphics card. My second thought was that I don't know anything about graphics cards, or computers in general, and will probably electrocute myself good and dead if I try any self-repair, but then again there are worse ways to die than preparing for Starcraft 2. My third thought is that someone here can probably take a look at my system snapshot and immediately tell me what to do:

Before settling on a card though, why don't you visit this thread in the tech subforum and have them advice you. Just tell them how much you're willing to spend on a video card, and give them the processor / ram and they'll double check for you.
I agree with putting a budget card in, at the ~$90-120 range. Neither of the cards mentioned will run demanding, new games at very high resolutions with maximum settings, but you should be able to coax reasonable medium performance out of most new games, and high settings for less demanding fare like Starcraft.
A much better buy than the 5750 and competitively priced!
