Which will win? multiple average gpu's vs. single high end gpu (for alt coin)

[Greendays]

I wonder if average or low end multiple gpu's cost too low comparing to high end single gpu,, will it be more profitable. Whats your experience!

You'll want to take this thread to to one of the Alt-Coin sub-forums. GPU's haven't been viable for actual BTC mining in years.
