I am using i7-920, 12gb ram and 3 NVS-420 video cards that supports 12 monitors for trading. After 3 months of using, the computer is ok but I really don't like the performance of its graphic.
I want to build a new computer whose motherboard can support 6 video cards ( dual dvi). It is so hard for me to look for a motherboard since as far as I know, X58 supports only upto 36 lanes. The budget is about $2500.
