Yes, 1140 is a big hit all at once. I had a little difficulty justifying the purchase of an item that cost more than my entire used tank set up set me back. You must have some other devices currently providing flow? Even one of them will provide plenty of flow but in the long term your tank will benefit from two of them. Why not try it with one and get another later to spread out the pain a little?
One thing I should mention is that the VorTech will make some noise at full speed, so if that's going to be an issue, keep it in mind. If you hide the dry side in a box inside the tank, that would eliminate the noise.
With respect to the surface wave, as mentioned at 4 inches below the surface the VorTech creates good agitation at the surface meaning good gas exchange/oxygenation, but no signifcant surface wave. This will cause less of an issue with your overflow than the surge of a wavebox.
