I would like to keep things under $160. Mail-in rebates are fine. Here are the few I've come up with so far. I'm wondering which one is the best to go with (best bang for the buck), and if there are any better alternatives. I'm not running the infamous Crysis, or worrying about max anti-analising and high levels of anisotropic filtering, but I would like to run regular, non-benchmarkey games at nice settings.
