When I went from my Rebel T1i to FF, I was amazed at the difference. There is more detail in the photos, higher ISO capabilities, better color, more depth. It was worth it to me and I am just a grandma that loves taking pictures. When I was debating last year about upgrading, trying to decide between the 60d, 7d and 5 D II, someone posted "there is a reason it costs more" - which said, of course it is a better camera. And it is. No regrets transitioning to FF.
What camera did you trade up from? If you're coming from an XT/XTi/XS/etc, yeah, it'll be a huge difference. But he has a Rebel T3i, which has an amazing processor/sensor...going from that to a 5Dc may not be as impressive. Don't get me wrong, I fell in love with my 5Dc, but it's not for everyone. He'd lose video, the amazing, screen, the more modern UI, etc...I quickly upgraded to the 5D2 for those reasons...

awesome, i'm taking a look at some sample images from some of the lenses you discussed and most were taken on crop sensored cameras, and they look phenomenal. mabye i should save the 5d for later down the road, as it is a great camera. i don't need it to produce good images. is the autofocus somewhat quick on these lenses too? with weddings and b-day parties it's about capturing it when you get the reaction of a child opening their favorite present or when the bride tosses the bouquet of flowers etc. not to come off as offensive but have you used some of these lenses? if so how do they perform?

the reason why is because i found on amazon a 5d1 is only about 600 bucks, but it's used and i'm not sure what the shutter count is on them
$600 for a 5Dc isn't roughly the going rate, perhaps even a bit on the high side of things...you won't miss out by passing on it. Focus will be the same...your Rebel basically has the same focus system as the 5Dc/5D Mark II. In fact, it's better on your Rebel because the points are better spread out, due to the smaller sensor.
You're not being offensive at all, that's a very valid question...I've not only used, but owned pretty much every lens we have talked about (with the exception of the Canon 17-55 2.8, which is incredibly well rated).
The Tokina is an amazing lens, sharp, fast, and incredible AF.
The Tamron was excellent, though I had an older version with an accurate, but annoyingly loud focus motor. The new VC version is supposed to have that fixed (though I haven't used that lens yet).
The Sigma 10-20 had blazing fast focus (I didn't mention it above, but if you want wide on a crop it's worth considering). The new version of this lens is a constant f3.5, making it a third of a stop faster than the 17-40L...not a huge difference, but it's worth mentioning.
There is also the Canon 10-22, which I haven't mentioned/owned, but it's been a consistently well respected lens.
I owned the 17-40L and sold it because it simply didn't impress me in any way. It was a good lens...but not a great lens.
Check out my gear list (including my "sold" section), and feel free to ask any questions about any of the lenses and I'll do my best to answer them
