Looks fine to me, that's better than 95% of the people here.

You probably could air cool that if you wanted. I have that same case, its good. I have 2 1080tis and they stay under 70C with MSI Afterburner controlling the GPU fans when rendering. So I would expect a 2080ti to run a similar temp with that fan curve. I don't use the CPU during rendering, so it stays cool. Odds are that even the 3900x likely wont help render times a lot, its just the way Iray works. But that CPU will be a champ for many other processes, including pic editing and other creative software.

Some might say the 1000 Watt power supply is overkill, but it does allow plenty of headroom if you wish to add a 2nd GPU at a later time like I did. Its not like the PC will ever actually use 1000 Watts and run up your electric bill.

 

Sadly, with 3 slots 2080 TIs EVGA XC Ultras), this turned out to be a furnace. Not enough clearance between cards for airflow. Exceeded 85c on top GPU. Rebuilding now with a Corsair 760T case and a new MOBO, MSI Meg. Allows for 2 slots between GPUs, for airflow, with second mounted in bottom slot, which still provides 8x/8x lane. Fingers crosssd

Imo, this is a stupid problem to have. Unless I'm missing something and they're starting to make graphics cards ridiculously huge, I would think that the knuckleheads designing some of these motherboards would take into consideration that ample space is required between slots to allow proper airflow for multiple graphics card configurations. It sucks having to buy a whole new motherboard just for that reason.

Pascal and Turing are very temp sensitive and due to that the board partners have started putting on much larger cooling systems. This has caused some of these cards to exceed the 2 slot standard. Add in that the XC Ultra is a factory overclocked card, which means it puts out more heat , and you have a real problem keeping multiple cards cool in smaller cases.

Full tower case didn't really help temps. Throwing a Kraken 240mm on the cooler card and a Kraken 360mm on the top. That should out an end to this

You need to be realistic here.   How much extra cost would be added to the Mobo's and computer cases for the general computer populace by those "Knuckleheads" when trying to design their boards to account for the .1 of .1 percent of the computer populace who put two or three 2080Ti's into a single computer case using an air cooled system.

There are some, but the vast majority of people simply don't need that, and companies need to target their sales.

My hat's off to nonesuch00 for even trying that!

Between two 2080 TIs and 32GB 3200 ram OR one 2080 TI and 64GB 3200, which would be better?

A bit late to the party, but for Iray purposes specifically - the two 2080Ti's + 32GB RAM would be the way to go. GPU and system RAM do not (currently) stack on Windows or Mac OS systems where Iray rendering is concerned. Meaning that you are effectively limited to 2-3 times your largest GPU RAM capacity in terms of how much system memory could ever be taken up by DS/Iray during GPU-based rendering (the 2080Ti is an 11GB card, meaning that the most system RAM you could ever expect to be using would be 22-33GB tops.)  So unless you're planning to have ~30GB worth of browser tabs open while rendering, most of that 64GB is essentially useless.
