Intel introduced its first proper desktop GPU at a time when the GPU market was quite volatile due to the massive chipset shortages and inflated prices. The Arc A770 is a surprisingly good midrange GPU capable of solid 1080p and 1440p gaming performance. During its launch, it wasn't suitable for certain games, but with the latest driver updates it has become quite a competitive option. It isn't super expensive ($350 at launch) and measures just under 300mm in length, just like the RTX 3080 Ti option we've mentioned above.
The Arc A770 is available with either 8GB or 16GB of GDDR6 memory, and we recommend going for the latter since modern games have become quite resource-heavy. It features a 256-bit memory bus, dedicated 32 Ray Tracing cores, clock speeds of up to 2,100MHz, and a TDP of 225W. It is a bit hard to get your hands on this specific model of the GPU, but if you are lucky, you can grab one for between $350 to $450.
