I thought about buying a new CPU and I heard bad things about the coolers that we usually get in the box with the CPU. I want to buy a new AMD FX 6300 or 6350. So I don't really know what should I do , I can't spend a lot of money , I already have to buy a new MOBO and CPU , and now coolers too , RAM too but thats not so important , so should I buy 1 120 cm and 1 90 cm cooler or 1 aftermarket cooler for the cpu ? Note: I don't have any case coolers:
