You're not going to do 4-way crossfire on a budget, nope. There are some sub $200 AMD boards with enough slots though spacing is an issues if you're not using cards with single slot coolers. For a budget look for a board that can do 3-way CF max, like this
Also keep in mind that crossfire does not always work properly in games with more than 2 cards. There can actually be a small decrease going from 3 to 4 GPUs (if there's any effect at all) if the game does not have a proper 4-way crossfire optimization. An LGA 1155 board for 3-way crossfire would be a little more expensive but might be worth it. What's your budget?
