Which computer should i get?

Well to distinguish between these processors you need to be perceptive in regards to what technology has been embedded in the processors compositions. The i7 is sheer brilliance because it has 4 cores to handle moderately demanding to high demanding desires commendably. It's more robust compared to the i5 but it's mostly recommended for intense gaming because it utilizes different components and this may result in excessive heat being extracted from the computer. However the i5 is currently an ideal processor for the moderately demanding needs/desires you have listed the heat may be diminished throughout computer sessions because it doesn't require an abundance of power.Furthermore it's 2 cores vs 4 that's the primary difference between these processors but i5 shall get you exceptional performance and i7 if you have a keen interest in gaming shall perform optimally. All the best :) I recommend the i5 since you aren't going to operate extremely demanding applications.
