No, you will be able to have the desktop stretch across both screens as usual, but you will have to set one gpu to default for certain programs, while the other defaults for things like games. (will just be slightly tedious and time consuming, but will work just fine)
I'm planning to build a new pc, So I haven't figured out the motherboard yet, for the Graphics
I'm planning to buy AMD FirePro W5100 & AMD Radeon R9 285.
So If I buy one monitor with HDMI & DisplayPort Inputs and connect the Firepro with DP & Radeon with HDMI, & I can change the input in monitor, Will this setup workout ?
So while using 3D softwares I can use Firepro & while playing games I can use Radeon.
Power consumptions are not an issue.
I use 3d softwares (solidworks, zbrush, modo, sketchup, keyshot, maxwell, etc...) & equally play games.
