i just ordered new system parts and for the motherboard i picked the gigabyte 570 sli model, i dont plan on running two cards anytime in the near future. is it bad to put a crossfire ready card in this motherboard? i really wanted to pick up a 3870, should i return that mobo and get a crossfire one or will it not hurt performance? not too keen on picking up an 8800gt seeing they are more expensive and loud.
