So I have the Inspirion 570 and a budget of up to $130 dollars, the current integrated graphics card (Radeon HD 4500) needs to be upgraded. I'm looking into something purely for high performance gaming and a long lifespan. NVIDIA seems to be the best brand from what I've researched, not just for their popularity but for their performance. I'm not an expert but I know quite a bit, I figured I would take a shortcut from searching measurements and compatibility by just asking some of you folks. Thanks in advance for any information.
