Found a refurbished MSI 780 Lightning on eBay for $399.99. I already have one and was wondering if its worth getting another? I would probably have to get a new PSU I only have a 750w right now.

It is up to you really. I wouldn't personally. I think your 750 is enough anyway if you do decide to get one.

I wouldn't simply cause I don't trust Ebay or Refurbs... But 750w would be enough for 2 780s  but O.o what's with the username xD just had to question that and the fact it doesn't seem like you use AMD @ all

I would if you want more right now. I trust ebay/amazon just as much as anything else online. As long as the seller has great reviews there is nothing to worry about.

I personally don't buy refurbished or second hand GPUs, but that's up to you. Whether it's worth it totally depends on your needs as well, if you want more power right now then that seems like a sensible upgrade to me. Your PSU (as long as it can provide enough power on the +12V rail) should be fine as well, 750W is plenty as long as you're not overclocking to high heavens.

Look at my sig. BTW, the Core clock is still relevant but the mem clock is at base

Okay, with overclocking you probably want to step up to a beefier PSU then. Still seems like a decent idea to me if you're comfortable with buying a refurbished card and want more performance.
