An Intel ARC 7 with 24GB of VRAM would be the dream!
But with a 6700K… there’s no official PCIe Resizable Base Address Register (ReBAR) support, or PCIe 4.0 support. (There are some UEFI patching workarounds that might be worth looking into.)
That would certainly be one of many caveats worth looking into if going Intel ARC… currently just the last gen ARC A770 16GB.
Intel oneAPI performance is good, but not CUDA good (see YouTuber “Hardware Canucks” testing the ARC B580 12GB). There is the ZLUDA project, but that shouldn’t get anyone’s hopes up based on its history.
And the Intel Quick Sync Video (QSV) encoder is amazing, it’s a legitimate contender with NVENC in some workloads, and it is sometimes the best in others. Would recommend looking for reviews and testing of QSV vs. NVENC/NVDEC.
AMD has the Radeon RX 7900XT 20GB and the 7900XTX 24GB. There’s ROCm and HIP support, but Hardware Canucks’s testing show AI is usually CUDA or bust. (ROCm support in many AI workloads can be lacking…) There’s also the AV1 encoding 1920x1082 AMD ReLive defect…
And the new Radeon RX 9070 16GB and 9070 XT 16GB with improved encoders, even for H.264 (AVC). But there isn’t any ROCm support yet…
Nvidia is so expensive, they took the G out of GTX…
and put it into the price.
The RTX 50-series has dropped 32-bit CUDA support, which breaks the old PhysX games completely. So the 4090 24GB (beware 12VHPW), 3090 Ti 24GB (beware 12VHPW), or 3090 24GB… definitely will need to look into a new PSU for handling the transient power draw spikes.

Given an infinite budget…
and you go for a thin client setup from out of left field!
Truly didn’t expect anyone to play an UNO reverse card like that!
Then I’ll… use my infinite budget to create some neutrino-based hybrid classical/quantum network infrastructure, so nobody’s ping is bad!
