Did I Just make a mistake?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Did I Just make a mistake?

So I found an amazing price on a set of Dura Ace 7850-50 Carbon Clinchers. Pulled the trigger and they are on the way! Then I read that 50mm wheels are miserable for climbing... But I live in Utah and thats about all we do because the only way to get away from traffic (or summer heat) is to head up into the canyons... An ordinary after-work ride I'll climb over 3,000 feet and last month alone I climbed over 40,000 feet. Climb, climb, climb, climb...

I'm currently running a fairly tired set of Dura Ace 7800 Box section aluminium rims, but should I have gone with the 24mm or 35/38mm carbon rims instead?

Well, they're not especially light, but they are supposedly fairly aero, and durable, too. If you're already a good climber, and it sounds like you probably are, they likely won't hold you back much. And the aero benefits will pay off on the flats. If you don't like them, and you got a good price, you probably won't take much of a hit on resale. Think of it as a win-win.

Don't forget the descents, too. What goes up, must come down. Might as well do it with aero wheels.

If you really, really, really want aero climbing wheels, get a set of these:

46 mm deep, 900g or so - for the SET. Of course, they'll probably set you back about $5,000.

Or you can just lose about 1 or 2 lbs.

Are the wheels round? true? spin freely? If so you'll be fine.

According to weight weenies, my old aluminum WH-7800 wheels weigh in around 1600 grams and the 7850-C50's weigh just over 1700 grams. So maybe a 120 gram difference. That seems pretty insignificant to me...

Well, at least they have metal braking surfaces.

There are guys climbing just fine on worse wheels. I'm one of them. OK, so I don't climb "just fine" but it's not the wheels that are holding me back. There's good wheels that should see you thru plenty of miles.

Agreed. They'll be insignificantly slower on the steepest climbs and the aerodynamics should be an advantage on any hill where you're climbing at more than about 10 mph - and much more of an advantage on the flats and descents.
