Hello, I have recently built my first computer, coming off console, and picked a HD 7870 as my GPU. Well in BF3, which is my main game, I get terrible FPS on LOW settings! I get an average of 55 FPS with a res of 1600x900, changing the res doesnt change anything, Ive checked, my components are:
AMD Phenom II X4 965 BE
Radeon HD 7870
Seagate 1tb HDD
Coolermaster 500w

Whats wrong with it? People have told me I should be able to play on ultra with 55+ FPS. Please Help! Thanks!
