I am building a system around a MSI A75MA-G55 mobo. I am installing it into a small lan box. So I dont have too have too much room. I can probably fit 2 slim Radeon video cards for the crossfire platform power. But I really dont want to use a double slotted card unless I really have too. Can anyone suggest the best power single slot solution to my system? I would like to stay with the ATI Radeon GPU because of the ATI chipset on the mobo. Thanks for any help in advance.
