No, I’ve been looking at the i7-8086k, but with only 16 PCI lanes and dual-channel memory it’s not worth it.
You’re right about PCI v2.0 vs v3.0. Not much of a difference when using 10 series cards, but maybe that will change with the 20 series? Not sure.
I’m seeing 98/99% GPU utilization so I know it’s not bottlenecked PCI bus-wise.
I’ve been looking at the 7820X due to quad channel memory and 28 PCI-e lanes, but it’s expensive compared to what I’ll gain… I think
Upgrading to i7-8700k/i7-8086k and OC’ing to 5GHz won’t give me much (I think) with only 16 PCI-e lanes and dual channel memory.
Even the 9900K will probably not be “worth” the price tag (I would need to replace motherboard, CPU and memory in any case).
Still, when the Pi5k+ hits me, I’ll probably reconsider it all again…
You know, when the “hardware-craze” hits…
