The pocket bearing (on the front of the mainshaft) is the biggest weak point. Being lugged (run at high load at <1800rpm) and the factory oil fill level are the others. Keeping your RPMs up and overfilling it will go a long way to prolonging the life of your tranny.
KTA has put 650hp/ 1400tq through his Getrag and I think it has held. It's all in how it's applied, just like dodgetkboy78 said.
