After several hours of reading up last night, and considering the price point I can afford, I've decided to go with the Overclocked Edition of the Sapphire Radeon HD 7850. I've seen nothing but good will toward the card, and I like that it's fairly strong while using less energy than other similar cards (or my current card).
I was wondering if anyone here was using the 7850 (or a similar card) and wondering if they could tell me how well it plays Skyrim? My current card will run it with everything set to ultra (except AA, which I leave at 2x or off) in 1080p with the High Res Texture Pack and other smaller packs (high res blood textures) installed, but it will often drop down to 40 FPS while in town or in heavy combat situations. I'm looking for a card that will run it closer to 50 or 60 FPS fairly constant.
