Keller,
You're here for the same reason I came 6 months ago. I've got a P2V+V3, 2-P3Pro's, 3DR Solo and the Mavic Pro. I now have 11 race drones, half of which I've built myself. I rarely fly my aerial photography drones anymore, I'm to into this new hobby.
This is a different world and it's much more exciting but it requires a lot more hands on interaction. First, with the sticks, you don't take your hands off these sticks or you crash. Crashing is actually part of the learning experience, you can't fly these things if you're not willing to crash. I spend much more time fixing and building than I do actually flying.
It's a tough hobby that requires a lot of attention. It's different than the Mavic because it's not a "firmware" or "DJI Go" update. It's hands on fixing, learning, flying, crashing and fixing some more. Many come and go as they realize what it takes to stay in the air.
Personally, I love it. I get frustrated from time to time but the excitement of actually flying like a fighter pilot might is worth the frustrations.
You can find racers with GPS capabilities but I don't know many that are flying them. In this hobby you want everything stripped down and light. You don't want additional components that will hamper performance. For GPS enabled bird you may want to look at the Storm quads (

I don't know anyone who flies them but maybe they have some forums you could visit. If you decide to jump in there are many here that are willing to lend a hand.
