Spider Farmer SE7000 680w or 780w?

[Worldwomble]

Last light post about lights for me I hope I have a 4 x 8 indoor tent with CO2 that I need to light approximately half of very soon.
There is a Spider Farmer SE7000 680w at my local shop that I could buy today or I could wait to get the upgraded SE7000 730w delivered.
Could anyone please tell me if there’d be much of a difference yield-wise between the two?

If that is the SE7000 version with the Meanwell driver, get it.

The new version comes with a SpiderFarmer brand driver.
