I want to build 12 Monitor System Using 3 ATI FirePro 2460 Cards. Each card supports 4 Monitors [ Dell U2412M ( 24 inch )- 1920x1200 ] http://www.amd.com/es/products/work...-3d/2460-mv/Pages/2460-mv-specifications.aspx Please suggest the motherboard having at least 4 PCIe X16 Slots, CPU, a good brand RAM & GB needed, a good brand Modular PSU with Wattage requirements & decent Case. My budget is around $2000.00. I already have the Video Cards, Monitors, Hard Drives, Keyboard, Mouse & DVD-RW. Also if anyone has 12 Monitor system, would you please share your specs ?
