Is this a good pc for this pricepoint?

That is a decent deal for the pricepoint. However, don't listen to the comments above. That CPU will not bottleneck. However, you do have better options. Also, the RX 580 fails to be optimized for many games, so you wont be able to see it's full potential quite often. Other than that, if you don't feel comfortable building, don't build. Cyberpower is a reputable company. Don't listen to people trying to pressure you into a prebuilt. To each his own.

You'll definitely want to build your own, it'll be cheaper per part, and you will know exactly what's in it.

I just build my pc 2 months ago and was very unsure beacause i dont know to much about computers but its really worth it, you save alot of money and you cant go wrong each part has its place its like lego for adults
if anyone wants a good site so you dont have to worry about getting the wrong parts go to hardwaredealz.com they have all price classes and the best prices in my opinion
