Dota 2 depends more on the CPU than the graphics card. Every pick cost $250 or less, ordered by video memory, so the rest of the budget can go to the processor.
This is a research roundup, not a lab test: GPU, VRAM and memory come from each maker's published specs; a missing recommended PSU is flagged, not filled in, and no figure here comes from our own testing.
