Considering building the following AMD A10 Godavari based system for gaming and configuring it as follows. Will this be a viable solution with the new features in Windows 10?
AMD A10 Godavari 3.9Ghz
16GB PC 1600 Corsair
Radeon R9 280X 3GB (Dual)
Radeon R7 250 2GB (in PCIE 2.0 4x slot)
1) Disable Onboard Audio in order to free up extra PCIE lanes in chipset which will speed up the PCIE slots (including the R7). Use AMD TrueAudio output.
2) Crossfire the APU R7 to the R7 250X in PCIE slot #3 into Hybrid Crossfire.
3) Crossfire the R9 280X's in PCIE #1 and #2 into Dual Crossfire.
4) Windows 10 SHOULD combine the Hybrid Crossfire R7's to the Dual Crossfire R9's.
While under Windows 8 this would have been impossible, a recent experement I tried with my Phenom II computer suggests that this could be a workable option. With Windows 10, I tried ENABLING the Radeon 3200 IGP which has been laying dorment since DirectX 11. Not only did it enable without crashing, it DID Hybrid Crossfire in with my Radeon R9. I'm debating taking the concept to the next step by seeing just how much GPU Windows 10 and AMD will let you throw together.
