I'm looking to improve my PC to be able to run triple screens - have an i7 3770/3.4 GHZ, 16 GB ram with an ASUSTek P8B75M motherboard. Certain I need new video card(s?) and a better power supply. I'm able to start from scratch if necessary but wondered it the present setup can be upgraded. Do you have any recommendations that will allow me to run Project Cars on triple screens, 1080p and a good frame rate?
