I've been looking at the ASUS ROG Crosshair VI to host a Ryzen 1800 X CPU. Overall, I like it. The onboard M.2 socket is a great addition for an OS drive. The generous number of USB connectors really appeal for all my peripherals, but I've hit on a snag when going over the specs.
There are two PCIe x 16 slots. If you use two GPU's you get x8 performance out of each, which is fair enough. BUT, the other three PCIe slots on the Hero are only PCIe x 1.
I have a single Titan X-Pascal, so I want to use a single x16 slot to use its full potential. However, I'd also like to add on a PCIe adapter card to host a PCIe SSD (or more M.2 cards) for my 2 TB Steam games collection. Issue is, the PCIe card for M.2's are all x4 cards and the mobo slots are only x1 speeds.
I could use the second x16 slot for this, but that cuts the speed in half for the GPU. Or I can use x1 speed cards, but they are typically for SATA. As I'm building a performance rig, that feels like a step in the wrong direction.
My trusty Crosshair V - Formula-Z board in comparison has 3 x PCIe 2.0 x 16 slots, 1 x 4 slot and 2 x 1 slots which works beautifully. I really don't want to fall back on spinning drives to get this system working, so am I missing any options?
Cheers.
