I bought a new PC after my old one died without realizing that it had a smaller case. So I'm looking for a good video card that can run at least Oblivion and/or Firefall at high quality with little to no problems. Preferably I'd like a card that can run X-COM/Skyrim/Planetside 2 at the same quality, but I'm only looking to spend $50~$80 max. So if this is outside my price range I don't mind getting a weaker card. I have tried looking up a good card via google, but I've been informed that not all low-profile cards will fit in my computer. So I'm confused on how to identify ones that will fit, so any advice on what to look for will be appreciated. I've updated my system specs on the board as well, so if you need any other specifics you'll have to tell me where to look to find them. Thank you for your help.
