Hi, I have a Radeon 5770 that can run dual monitors. There's also a Radeon 4200 with Sideport mem on my motherboard. Should I run both monitors from my 5770? Or should I run my main on 5770 and the smaller monitor from the onboard video card? Does running a 2nd monitor on the 5770 use enough resources to make a difference?
My main monitor is 1920x1080 and my secondary monitor is 1280x1024.
It doesnt really matter, i have the same setup running off of a 4850, it seems like the desktop doesnt require enough processing to make a notable difference in performance, you can try it both ways and test a few games and see if it makes a difference but it shouldnt be significant if you arent spreading the game across both of them.
