The Steam Hardware/Software Survey [0] answers this.
Look up the MSRPs of the most common GPUs. Very very few are over $1,000. If you want to interpret "multithousand" to be >= $2,000, then the answer becomes VERY small (less than 0.5%), as the highest MSRP gaming GPUs are the RTX 5090 and RTX 3090 Ti, both which technically have an MSRP of $1,999, that typically only applies to the "Founders Edition" releases done by NVIDIA. 3rd party AIBs (MSI, Gigabyte, Zotac, etc) typically charge a bit more.
