Hi, I have no knowledge whatsoever on computer hardware and I'm wondering if I can upgrade my A6-5400K Trinity? My computer broke down a few months ago and I was looking for an affordable comp and I stumbled across the A6-5400K. However I realized after running on it, it is substantially slower than my old computer. Not only for gaming, but I can barely surf the internet without little lags and delays. Should I upgrade the graphics card? How should I do it? Or is the slowness due to too little RAM?
