Question Building system with i7 10700F

Whats the best What???
I might guess you are asking about a motherboard.
I do not know prices or where you may shop.

Most any lga1200 motherboard will work if you need nothing special like wifi, slots or...
I might add that I would try to buy a non F suffix processor.
Graphics cards are hard to come by these days, at any price.
At least, integrated graphics will let you do anything except fast action gaming.
