The problem with Dell is almost everything is proprietary connectors etc. My sequence of events:
Plan A:
Thought I had a pretty good system, Dell Optiplex Tower Plus 7020, 64GB i9-14900K core, and an NVIDIA GeForce RTX3070 or 4060, cant remember. The 7020 is a Gen4 PCIe bus. When I dont have a camera in my hand, Im on the computer and seems like I never shut any program down. I started having lock ups when running PS and Topaz would just drop trying to do save text with airplane photos especially. I wanted to get an RTX5080 Gen5, but since the case of the 7020 would not accept a 12 in long video card, I planned on mounting it externally with a PCIe extension cable. Duh, cant be done because the Dell 7020 power supply cant be upgraded to the 1000W the 5080 has to have. All the Dell pinouts are proprietary and different between power supplies and motherboards. Fallback plan, NVME M.2 M Key to OCuLink which has its own power supply for the video card. Could not make that work, close but no cigar, it would work once, then quit working completly. OCuLink is used by gamers to add external video cards to gaming laptops.
Plan B:
Shopped around and decided to try the Dell Tower Plus EBT2250 64G Ultra i9 285K and GeForce RTX5080. The EBT2250(nonAI) is PCIe Gen5 as is the RTX5080 which has 16GB of memory. I dont begin to understand the Dell product lines which seem to always be changing and takes up so much time to pick one. I almost went with the Alienware, mainly because they offer a liquid cooler, but really didnt need all the flashing lights and transparent case. I thought the 7020 always ran hot, so I added a couple of case fans to this EBT2250. Bottom line, Im pretty much satisfied, although I think maybe the RTX5080 could use more memory. (sometimes I have 10 to 15 photos up at one time in PS) I dont try to run my video intensive Schwab thinkorswim trading platform at the same time as processing photos because it has locked up on me once with Topaz. Truthfully its a crap shoot with a lot of moving parts for ones particular set of requirements. Google best photo editing computer and start from there!
Edit: The RTX5080 has the option of "Game Ready" or "Creators" (graphic designers/photographer) drivers.
The RTX5090 has 32G but is pricey at $2500-$3700
