A lot depends on how you want the top of your tank. I wanted perimeter bracing only and my builder said definitely 1" acrylic and no less than a 6" perimeter for a 84"x36"x28" Stepping up to 1.5' I would have been able to get my perimeter down to 3"-4" but it added an additional grand to the overall price. Going from 3/4" to 1" is a big price jump, but going from 1" to 1.5" is serious coin.
Either way, with this being my 4th acrylic tank I'd never do a tank such as you are describing in 3/4". I just can't believe that you wouldn't start to see some noticeable deflection on your sides after the tank had been in place for a while. There's nothing worse than dropping several grand in a tank and having it start bowing on you 6 months down the road.
