I'm trying to build a PC which can support atleast 6 22" screen and also in future if I want I can also add 2 more screen. The use of the PC will be for trading shares and I won't be playing any games.
The only thing I'm not sure is graphics cards and motherboard. I think I will need 3 Graphics card (may be GT520?). Is it enough for 6 monitors and also if in future wants to add 2 more monitors? And also which motherboard should I go for (Asus P8Z68-V PRO/GEN3).
I'm not an ATI user and would never personally need more than 3 monitors but there is an ATI Radeon HD5870 Eyefinity 6, that can run 6 monitors on 1 card. You would likely need a second card for 2 more. That would save you money, heat and power.
