Best NVIDIA GPU upgrades for Dell Precision 3620 Tower?
I have a Dell Precision 3620 tower with an Intel i7-7700K CPU. I recently upgraded to a 750 watt fully modular SeaSonic Focus PSU, which has the ability to support GPU power cables.
I want to upgrade to the most powerful NVIDIA GPU that my system can support without modifying the case (I do not want to remove drive bays, for example.
Here's a picture of the interior of my computer:
The image is outdated (it was taken before I upgraded my heatsink and PSU and moved my Wi-Fi card down to the bottom PCIe slot to make more room above), but it should suffice to give a good idea of the size constraints I'm working with.
The biggest issues in terms of space, that I can see, are the USB 3.0 connector, SATA 0 connector, and SATA 3 connector, as they all stand in the way of installing a GPU that is longer than about 160-170mm if it is thick enough to extend that far down. This puts a definite hard limit on the size of a GPU that can be installed in my computer without modifications (or perhaps even with them).
What are some of the most powerful NVIDIA GPUs that will fit in my case without modifying the case (especially considering the position of the USB 3.0 connector, SATA 0 connector, and SATA 3 connector), are compatible with my 750 watt SeaSonic PSU, and are available for $300 or less? I'd also like as much VRAM as possible within those limitations (ideally 12GB or so, although that may not be possible).
It's also absolutely necessary that any GPU that I get be compatible with the latest versions of DaVinci Resolve (which require CUDA 11, which is supported on GPUs with a Compute Capability of 3.5 and above).

Some cards are double slot and a half. They could interfere with those USB cables as well.
I would not worry about bottlenecking or elaborate on solution for issue that not yet happened. For the best upgrade with your budget and met your requirements as main topic query, I suggest to consider the Asus Dual . Check the sale term and verify that you have 30 days for testing and return it for full refund if it does not work out.

Here's an up-to-date image that I just took today:

For a budget of $300 USD, you may consider RTX 3060 with 12GB of GDDR6. Some dual fan variants of MSI and ASUS will fit just fine without the need of removing drive cage.

@Chino de Oro
I looked up this one (which is one of the most prominently-sold ones):
https://www.msi.com/Graphics-Card/GeForce-RTX-3060-VENTUS-2X-12G-OC/Specification
The specifications are listed as 235 x 124 x 42 mm. Wouldn't 42 mm be thick enough to cause a GPU that long to bump into the USB 3.0 connector, SATA 0 connector, and SATA 3 connector?
Another prominent version, the GIGABYTE GeForce RTX 3060 Gaming OC 12G (REV2.0) is almost as thick (41mm) and longer (282mm).
The ASUS Dual NVIDIA GeForce RTX 3060 V2 OC Edition 12GB GDDR6 Gaming Graphics Card looks like possibly the most promising candidate, as it's listed as 7.87 x 4.84 x 1.496 inches/20 x 12.3 x3.8 centimeters.
https://www.asus.com/us/motherboards-components/graphics-cards/dual/dual-rtx3060-o12g-v2/techspec/
Do you think that one would likely not bump into the USB 3.0 connector, SATA 0 connector, and SATA 3 connector (keeping in mind that said connectors are around 160 or 170mm away from the back of the case, as far as I can tell with my measurements)?

Double slot cards should fit without interference with those USB connectors. Larger cards have been installed and benchmarked by users https://www.userbenchmark.com/System/Dell-Precision-Tower-3620/21304

@Chino de Oro So, as a general rule, would nearly all double-slot cards fit without interfering with the connectors? That is to say, are the connectors only an issue with triple-slot or bigger cards, or are there some double-slot ones that could still be too thick?
Also, is bottlenecking typically an issue with a GPU as powerful as a RTX 3060 when paired with a Dell Precision and an i7-7700K CPU? If so, can it be solved by simply setting the GPU to slow down to match the CPU?

@Chino de Oro
It does look like the most compact option that meets my requirements.
Unless I find something else that's better first, that's probably the one I'll order.

Hi @Rocketeer
Did you manage to fit the Asus Dual successfully? I also have this Dell tower and need to upgrade from the Quadro K2200 to something at least 'Feature Level 12_0', which I had never heard of until yesterday! Also, do you know whether this card would require a new PSU?
Thanks!

@Ian-g2040 Yes, I was able to fit it successfully, albeit just barely. The latch on the back of the computer presses against the GPU, but is still able to just barely close. Other than that, it fits easily.
It does require a PSU with at least 650 watts. I bought a SeaSonic Focus 750 watt 80+ Gold PSU. SeaSonic makes the most high-quality PSUs, followed by Corsair. 80+ Gold certified PSUs in general are the most reliable grade of PSU.
I also bought this 24 Pin to 8 Pin adapter to make it compatible with the Dell motherboard:
