QB304s on one 320h or two?

I have 4 QB 304s running off one 320h-C1400b.

Should i get another driver to run these boards? Ive had a few successful grows and feel like any brighter than about 83 watts (my max watts) per board and my plants will burn. I keep them 15-20 inches away, but i feel like if these 304s had max power i would want them 4 feet away.

Sometimes i feel like these 304s are overkill for me and i wish i just had 4 QB 120s instead.

What watt per board do you guys run?

I run my 288's at 100watts each at about 23inchs from the plants. Any higher and the heat is to much for me.
