Nice. You got enough power in there for 2 3090's.

@Howard-Vigorita I guess I could, but I will not!

I focused my build on both performance and silence, 2 things hard to combine. My PSU is 1500w capable, so plenty of juice for alder lake and 2 Graphic cards. Using a second graphic card in the Z690 Aorus master motherboard would mean that second card is not directly talking to the CPU but has to go via the Z690 chipset and then via DMI 4.0 channel to the processor, not ideal, a bottleneck and shared with other resources (although not as much as in legacy systems with DMI 3.0). Furthermore, a second card can only operate in PCI express x4 mode in a PCI express 3.0 bus while the first (main) card can operate in PCI express x16 mode in a PCI express 5.0 bus (or lower) talking directly to the CPU...

Talking about silent operation, the reason for my over-dimension of the PSU is to be future safe, stable and silent as the PSU fan only kicks in above low and medium loads. The higher capacity you buy, the longer it will take before you here a fan...

Another silent component is the fractal design define 7 PCGH edition case, and the Noctua NH-D15s CPU cooler.

And the last silent component is the ASUS GeForce RTX 3090 TUF OC GAMING which has also a zero-fan mode at low load, and a dedicated HW switch on the card to select a second BIOS for silent mode. By default, that switch was set to performance, I switched it too silent mode.

@RogerS Yep, soon!

This is the only thing keeping me wanting to stick with an AMD CPU when I upgrade, those additional PCIE lanes. VEGAS performs better with Intel in pretty much every other case, though.

Got the same CPU cooler, both my PSU and GPU operate like yours, mostly no fan. The loudest component is an old AMD CPU cooler that I use for my VRMS, stays 15% speed normally but ramps up when CPU is drawing peak wattage - Needs replacing

@RogerS I have submitted my results in the web form;

Here is a summary of the Vegas benchmark/

Note: all run default, no overclock, however I had to disable all 8 slow E-cores (efficient but slow atom, no hyperthreading), so my Alder Lake system of 16 real cores is running in 8 P cores only (or I get much slower renderings, actually slightly slower than my old system) ...
