I'm looking to build a gaming pc with a low budget so i'm trying to save as much money on every component. My question is would it be better to crossfire say 2 cards with one gb of ddr5 memory and about $100 each or to buy just one $200 card with 2 gbs of ddr5 memory. My biggest questions is does crossfire only work with 2 displays or can it be used with just one? If you know anything about this please feel free to post!
