Hello, I am planning on getting a graphics card for medium amounts of gaming. My resolution is 1600x900. Processor: Phenom 2 dual email@example.comGHz. 500w psu. 12 gigs of memory. Currently have an integrated AMD Radeon HD 4200. (Bad, I know.) And I know that for around $110 this card is overpriced. But... what about for $90? I need a card for under $100, if you have any other recommendations.
