Well I will be playing other things of course, I just think of TF2 as the baseline for my performance needs. It's also the game where my new 120Hz monitor would make the biggest difference (so I want to make the most of it). Overall though, I don't need anything too amazing, I think the 6950 might be overkill.
They actually don't have a 6950 at my nearest microcenter, only a Diamond 6970 @ 299.00
To clarify, TF2 is really the only game I want to cap. Besides that, I usually play RPG or indie games, and with the exception of TES modding I dont think I'll be playing anything else too demanding.
On that note, would a 2GB card be better, for Skyrim/Oblivion HD mods? Are there any 2GB cards <$250?
