I'm getting a two year old computer (from a trusted seller) and was looking to upgrade the hardware. I went to a mediocre computer store and asked to see some of the parts I was looking for and the guy asked me some questions. When I told him the computer was 2 years old, he told me I'd also have to replace the motherboard. Is this true?
And for future refernece: how long should I keep and use a computer for before replacing the motherboard and other hardware?
I'm planning on using this computer for primarily gaming and using the internet. I want to replace the processor, GPU, and add more RAM.
