hi i have an acer aspire xc-215 and the current graphics is amd e2 6110 apu with radeon r2 graphics. i want to hook up 3 monitors to my desktop for trading and have been told i need a graphics card but dont know what is compatible. Maplins said i need low profile but im not sure if that is right for my model. any help here would be great as i am lost with it all now. thanks
