Whether to use a graphics card depends on how many symbols one trades. If you want to trade just Nifty, (and/or BNF) then even 1 monitor is good enough.
If you want to trade more than few symbols while NF and BNF continuously run on another monitor, then you would require multiple monitors.
In my setup, I have NF.BNF on 1 monitor. On another monitor, I run the scanning script. On another monitor, I run trading platforms.
So once you decide on how many monitors that you would require, then question is which graphics card or is the internal graphics available in core ix processors good enough. There will be some performance hit if internal graphics engine is used (my thinking!!). So, for supporting multiple monitors, it is better go for a graphics card for minimal load on the CPU. Further, most of the charting software do not use the complex graphics rendering which means again the reliability becomes preffered spec to look for. For the same reason, it is just worth to go in for a workstation graphics card.
For 4 monitor support I use AMD Firepro W4100.
