Will running Windows 8 shorten rMBP life?

I've read that due to driver compatibility issues, the rMBP utilizes only discrete graphics when running on Windows. Also, the laptop runs really hot when I'm watching videos and playing games on Windows.

Will this significantly shorten the time until I'll need to replace my rMBP as opposed to if I run it exclusively on OS X?

Due to Apple's emulated BIOS, the discrete graphics is the only graphics seen by Windows. You could eliminate that issue by booting using UEFI but I heard there are troubles getting the integrated graphics and sound to work due to the integrated drivers.

So yes, rMBP will reduce the battery life in Windows.

Generally heat will always hurt the life time. Especially the battery. But at the end of the day if you use it a lot it also pays for its price much more. Not using it for stuff you want to do just to preserve it won't do you any good.
Just expect to replace it in 3-4 years and even under lots of full load it should last you long enough.

It is definitely not a good idea to use Windows all the time (better to get a Windows notebook for that usage) but if you need for gaming it will survive long enough until it will be such slow outdated hardware that you will want to replace it anyway.

SMC fan control.
Set it to higher RPM.
Reboot straight to WIN.
Your laptop runs cooler now.

Yes and it so enjoyable having fans running full tilt while you just watch a video. Right now it is so hot here I am glad I can just use the IGP in OSX and watch videos at bearable 3-4000 rpm while just turning the dGPU on almost necessitates full speed.
30C room temp sucks.

When playing games smc really doesn't make a difference as you have full speed fans anyway.
