Hi, I've been debating on which of these to get. I won't be playing THAT many games (as of now) but I do play Flight Simulator X every so often, and I also do some 3D modeling which requires a decent video card for rendering. I don't do huge production renders, I just want to be able to model without having my video card stick and show artifacts. And sometimes when I'm bored, I want to be able to have smooth frame rates in my occasional COD Nazi Zombie massacres. My budget is anywhere between $150 and $220 so yes, I know, I won't be able to afford a high-end card. I just need something substantial and for it to be the best value per dollar spent. As for a brand, I've been hearing that EVGA is pretty much top dog. I want to go for either an EVGA or an Asus, which seems decent as well. Can anyone help me out here?
