An Argyll is fine for black tie. But rather than a wing collar AND straight tie (which would both BOOST the formality w/wing collar and REDUCE it - straight tie), you might wish to consider a full collared shirt (turned down collar, plain pique front - no pleats) and a basic black (self tied) bow tie.

If you're sold on the straight tie look, definitely go with the turned down collar.

HERE'S a pretty good guide to the basics of black tie.
