Hi guys,
Because I have been reading contradictory information on the subject. I decided to test it myself.
It still seems this article, and logic would make me agree with it.
https://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_1080_PCI_Express_Scaling/25.html
but some are reporting that it does make a difference at 4k and above. So I wanted to test it, and wanted others to use as reference. A Dell 4k Monitor will be used.
Here's the issue:
Because there is a 970 GTX being used as a dedicated PhysX card, and a 28 lane CPU is being used, the slots will be limited to PCIE 3.0 8x. I am curious to see if there is an impact to the 1080 GTX's in SLI running at 8x. A Nvidia HB 2 Slot bridge will be used on the GTX's.
I am testing a Asus Rampage V V10 with a 6800k. The 6800k was chosen, because there didn't seem to be a real reason to go for the 6850k and the 6800k was on sale. I hope not to regret that decision. But because that was done, we can't have all slots at 16x. The purpose of this to to test if that will affect gaming at 4k resolution and or above (using scaling).
Bonus Question: Previously this rig was using 4x SSD's in Raid 0, which gave a 1k R/W performance. I intend to continue using that. However noticed the M2/U2 configurations being popular now, and makes sense to have a direct connection to the PCIE. Will this PC suffer from having the 4x SSD Raid on the Sata Controller? And what are the pro's and cons vs M2, U2. Obviously not having the liability of Raid 0, but wanted to know if there is any other technical reason. I presume the bandwidth taken from the CPU is from the same place? Just different more convenient form factor not needing raid?
Please post suggestions, and scores for testing. I am planning on testing using UniEngine and any other suggestions here.
The PC is not yet built, so please give it a few days, awaiting backordered fans. But wanted to start gathering prelim information, and knowledge of people with similar setups.
Cheers!
