I'm a bit of a noob when It comes to Graphics cards and im looking to upgrade my current graphics card to something better. I currently have a 1gig DDR5 amd Radeon 6850. I'm looking to be able to play newer games like bioshock infinite with the textures all the way up and run it at 1080P and get 50-60 FPS. With my current card I get i get about 20-30FPS. Should I get a second card and crossfire or upgrade to a completely new card? If so what would you recommend? Im only looking to spend around $200 on the card. I'm also planning on buying a new motherboard and CPU as well so I am open for suggestions.
