So I have an Acer AX3400G-U4802. I know its dated but, I'm looking to upgrade this machine. I have a 2TB hard drive and was shopping the AMD Phenom II x6 1090T Black Edition CPU. I'm looking (if possible) for a graphics card that will support multiple HDMI. I was wondering what would work best with out bottleneck? I'm okay with a new power supply if needed.
