Hey, I'm in the market for a new graphics card, I've got a pretty decent PC besides my current card which is a NVIDIA GeForce 7300LE+, it sucks with anything dealing with shading, and whatnot.... Anyway, so I'm wondering what's good on the market right now for cards, something that will last a few years at least. I'm willing to spend anywheres between like 250-500ish.
