I've had problems with the R9 270x..had to RMA 3 back to back due to different reasons. I have little faith in AMD after all that. I am thinking about Nvidia mainly the GTX 760 it is a nice upgrade from the 270x...but I am also thinking of the 280. They are both around the same price and it seems the 280 is better than the 760. Here is my thing, I am worried about AMD crapping out on me again and the power limit. The Evga GTX I am looking at needs around 500W and the Gigabyte needs around 600W...I have a 650W 80+ bronze psu from Rosewill. Which one should I get...will my psu be able to handle the 280?
