Currently have a Zotac GTX 760 Amped! edition 2GB card. I'm looking at buying an MSI GTX 760 OC Edition 2GB card to add to it since a good friend of mine is offering it for $40. I'm running with a 650w Corsair PSU and an i5 4670k @ stock speeds. My two questions are will my PSU be able to handle this? and secondly, at stock speeds, wil lthe i5 be a bottleneck? I'm thinking the answer to the second question is a definite no but if I do need to OC I'd most likely need more than 650W.
Going to be adding another card in SLI. Will my PSU stand up to it?

The 760's TDP is 170W, so two makes that 340W. Plus the CPU's TDP of 84W makes 424. That leaves plenty of headroom for any overclocking.
And I really doubt you'll see bottlenecking. Though, I'm not entirely sure how SLI and bottlenecking go together. But personally I wouldn't worry about it. And if you do have any problems, the 4670K will overclock nicely to around 4.2Ghz without much heat.

It will depend on the exact model of Corsair 650W that you have. If it is a CX, it may not take the load w/o its capacitors failing. And if each card requires a 6 pin plus 8 pin, be sure your PSU has those.
The i5-4670k will keep up with 2 x GTX 760 just fine. No bottleneck. Yes, I would hesitate OC'ing anything with a 650W PSU running 2 x 170W (or more) cards. It's probably OK, but that's just me.
Be sure your motherboard does SLI at X8, x8 lanes at least. Some boards drop the 2nd slot to x4 lanes. That would be a performance killer and might cause scaling problems.
