performance at a given resolution doesn't mean anything zero nothing - a game from 10 years ago will run on the most basic system at a high resolution where as a next gen title will NOT - resolution means nothing
overheating never worry about it - buy your system, test it at 100% load, if your system crashes look into it from there
stock components should work with stock coolers, if not its a factory defect - return the item as not working as intended - easy
Thank you for your answer , so looks like ill be going for the system as i wrote it . Do you maybe know how this cpu goes with Dolphin emulator ? i know intels are better for that but they are much more expensive than what Amd has to offer...
