I mainly play BF3 and i want to get at least some 5-10% performance boost to enable MSAA. As far as i researched, BF3 supports crossfire pretty well, doesn't it? I chose crossfire over a new card because of the price (100 € compared to >400 €).
I was wondering whether each P7P55D mainboard (it was pard of a gaming pc i bought some 2 years ago) has enough space for two 5850 without any fancy cooling customisations etc.?
