With some fine tuning, and since AMD cards are more efficient than before, mining with GPU can be a way to go with current altcoin price, but it still depends since no one knows what will happen next to the altcoin prices.

One more thing, if GPU mining becomes outdated, it can be sold to budget gamers as a plan B to get back money, unlike ASIC machine, if the hardware outdated it will just become trash and no market value.
