SNAR :
So far, this is what i have read/heard:
Amd processors and GPUs are Cheap but consumes lot of power. Heats up fast. Becomes noise over a certain period of time.
How much are these true?
Exactly what 12 year old Intel Fanboys would say, however it's partially correct.
It is a known fact that AMD GPU's usually have a slightly higher power consumption compared to the Nvidia counter parts. However your electricity bill will barely change, if you are a hungry user you will have to spend $10~$30 more per year if you use AMD GPU's. As for the heat again AMD GPU's are known to run slightly hotter than Nvidia GPU's and it is safe. I would say GTX GPU's are safe up to 85C and AMD GPU's are safe up to 90C. The fan noise really depends on...
