Nice. X870 has pretty much everything I'd want in a platform. That wasn't the case with X670. It lacks the 16xPCIe5 connectivity which is something I would want in a computer that I'll keep for many years. The things that X870 loses vs X670 (less USB, SATA, PCIe lanes) don't really matter to me.
They have pci-e 4.0 x16 which is the same bandwidth as pci-e 5.0 x8 there are no pci-e 5.0 graphics cards
I read a while back that the 5070 would be PCIe5.0x8. Latest rumors say it's 5.0x16 but if some cards release in the future with only 8x PCIe I think it'd be best if those were PCIe5 lanes. 4.0x8 might cause some issues on say something like a 6060. This is one of the reasons I got a Z790 even with only a 13600K. I have an irrational fear of bottlenecks.
You gonna get a 5080/5090 when they come out?
Yeah, agreed with this after about two weeks of tinkering. I'm back to air cooling for this generation, using a Noctua D15 with the dual 120mm fans. I've been using y-cruncher and Cinebench to estimate where my best performance comes from, and both single + multicore results always seem to favor memory at 3100 MHz CL30 (6200 Mt/s) with UCLK 1:1 and FCLK at 2066 and the CPU undervolted by 25mV on all cores. I can push a 100MHz overclock with a little less undervolt (only -20mV) however the temps step up by several degrees while benchmark results are within the run-to-run error variance of stock clocks. At a 200MHz overclock with -10MHz undervolt, any all-core benches run into the thermal limit at 95*c and the benches actually go down. Single CPU is finally measurably faster than stock, but only by just a few percent at best.
