This list is very useful to understand how u may crossfire between two cards.

i want to experience a small boost of gaming with cheap stuff. i got crossfire mobo and x1600xt. i want to buy a another x1600xt but cant find it. so i decided to buy x1650pro which seems same asx1600xt but 80nm technology which is low heat i see in the list it is possible to crossfire xx1600xt and x1650pro but not best crossfire solution. no is cheap .
