Git is great for smaller binaries. Ideal in fact, given that it stores differences between revisions as binary deltas. For large >1GB files, I believe the diffing algorithm is the limiting factor (I would be interested in getting confirmation of that, though). For those files something like git-annex is useful (http://git-annex.branchable.com/)

I've used git to push around a lot of binary application packages and it's very nice. Previously I was copying around 250-300MB of binaries for every deployment--after switching to a git workflow (via Elita) the binary changesets were typically around 12MB or so.
