Dedicated vs. Discrete Graphics

[perryh]

I don't know anyone here that wants to use a touchscreen for work, you might try support before they close today. Myself, I would not use an integrated video card.

John - im running chief x4/ x5 on sony highest end vaio Z (1920x1080 screen with i7 3612QM processor)
thats without the external graphics plugged in via optical cable back to notebook etc.
so im only with intel hd4000 and it runs more than fine for general chief stuff including 3D.
I run 1 external monitor. (can run up to 4 independent)

rendering with intel hd4000 ?? - can be done, works, but far better with nvidea (1st choice) or radeon (2nd choice) discrete graphics as it halves the time.

hope that helps.
Bernie.
