Why do you need a wide angle lens?  Why that range of focal lengths?  

Why that aperture size?  What are you trying to photograph?

If you can answer those questions, then you should be able to answer your own.

17-40 is wide angle on a full frame body but it is not a wide angle lens when mounted on a crop body. Your standard kit lens for crop is 18-55 and 1 mm difference on the wide end is no difference.  A 17-40 makes little or no sense on a crop; you are just chopping off the 41-55 part of an 18-55.  The 17-40 is an L lens so it is more rugged but it is not a terribly sharp lens and not a lot sharper than the kit 18-55, and the kit lens has image stabilization.  

Wide angle on a crop body are the EF-s 10-18 or 10-22 or similar lenses.

What Scotty says is right.  But the 17-40mm f4L makes a very good normal lens for the 800D. I used one on a Rebel for years.  It made me a lot of money so I can't fault it. The 16-35mm f2.8L is better although more expensive.

If you want a good normal zoom that is a pro level go ahead and buy it.  You won't be disappointed.

The advantage of the 17-40 is that it works on a full-frame camera. If you're not going to go FF in the foreseeable future, get the EF-S 17-55mm f/2.8 IS USM instead. It's a stop faster, gives you more reach at the telephoto end, and probably has at least as good image quality.

What lenses do you already have?  If you have an 18-55 or an 18-135, are you wanting a wider field of view than the 18mm end of your current lens?

"If you're not going to go FF in the foreseeable future, get the EF-S 17-55mm f/2.8 IS USM instead."

The single reason is, if a person wants a stronger built lens for whatever reason.
