The old saying, "you get what you pay for" holds true. The performance of these cheap motherboards is good, but the components that are used to keep the cost down are not great quality. Hence, oftentimes these motherboards have reliability and durability problems. Even though some manufacturers offer decent warranty coverage, getting an RMA and pulling a motherboard is a PITA. For me personally, it is just not worth the risk.
~$250 or ~$280 is such a budget board. I agree that sometimes you get what you pay for, but the board I linked was reviewed well. Do you get 47% or 64% better performance over the $170 mobo?? I don't think so. That is the price premium that your spending over the $170 mobo (47% on the Asus and 64% on the Gigabyte mobo's). Even the Asus and Gigabyte mobo's have failures too (maybe less), but they do fail too. Now Asus has been having some RMA issues as of late, so I'm not too hot on them recently (I think they sold out part of their mobo business in the last year, IRRC). So when someone asks for a good BUDGET mobo, I think to myself, what is a good price and has good reviews too??
