So I've had my version of the Acer Aspire V5 (the 551 series) for almost 3 years now. In terms of performance, it does pretty well for as old as it is. However, it has had some major problems in the time that I have had it, like the display on the screen being broken, as well as the optical drive breaking as well. When it was newer, it did pretty good in terms of performance, but it is in NO way a high performance computer, if that's what your looking for. If you are planning on doing anything that's CPU intensive, I would suggest staying away from this.
This computer has a core i7 and nvidia 750M ,not really a gaming pc or editing pc, but it is good at gaming and editing videos ,the screen is also super clear. it has 4 speakers .i do really recomend this computer
