Re: Need Video card suggestions.
Your best bet is to get something from the Antec line, like the Antec 300 or 600. We use the 300 here at my office and it fits most of the larger cards just fine.
As for power supplies, since your GPU isn't that demanding, a 500 or 600 watt Corsair should be plenty. If you want to save a bit of cash, Antec has some nice True power 500 watts that would also be fine.
