Six 105w chips on a than that's about 100 gallons? I don't run that much light on my 125 gal reef. I'd say you would be way overpowered.
They also cost $108 each, not exactly cheep. You would also need to add some sort of power supply, and a massive heat sink for each one. Optionally you may want some kind of control system. At that point your into quite a lot of money and you could get several off the shelf lighting fixtures, plug them in and go, for a lot less money.
For example, on my 90 gal planted tank, similar in size to yours, I use two Current Satellite + Pro fixtures. They are about 60w each, and I get good light. If I wanted more I could add an additional fixture. They cost about $288 each, so you'd come in well under your budget, and you just need to plug them in and set them up.
