I would not read too much into the Intel onchip/onboard graphics. It is just not that important in trading applications. The graphics performance may be more important for laptop users, who relies more on the onchip/onboard GPU. On a desktop, you can easily buy an external video card (some are very inexpensive too), and probably would disable the onboard graphics any way.
In trading, drawing candles and squiggy line indicators are all 2D applications. Not graphics processor challenging.
