Most stores sell it for much more than what you can get online. With mail-in rebate, these things are the best prices you'll most likely see. The GT 240 is more or less the same as a Radeon 5570, which is just a teeeeny bit slower than a 6670. And it's dirt cheap. I'm not so experienced with nVidia, but yea, it seems like the 430 might be close. I'd go for a Radeon though, that's just me.
