Is this a good prebuilt gaming desktop?

I am looking to buy a prebuilt desktop for 1080p 60fps gaming (e sports and "AAA"). I have found an Acer GX desktop for $1300 AUD ( ~ $1000 USD). The specifications are:

i7 7700
16 gb ddr4 ram
1 TB HDD
256 GB SSD
500 W Power supply
Gtx 1060 3 gb.

These are the best specs I can give. The part manufacturers aren't mentioned.

For the price, the CPU, RAM and SSD are good imo but obviously the 3gb gtx 1060 is a concern. I am aware that rx 480/580 or gtx 1060 6 gb would be better but I don't have that choice since its a prebuilt.

Would you guys still recommend getting this? I have seen better deals on prebuilts but they ship from US so import taxes make them not worth it. I can get this locally in australia so shipping is very small cost and no import taxes. Other desktops around this price range might have rx 480 or gtx 1060 6gb but they will have i5 6400 cpu, 8 gb ram and no ssd which seems like greater shortcomings than the gtx 1060 3gb imo. What is ur opinion?

Thanks.

I agree that the power supply seems to be low wattage for a system like that. Its probably "adequate" but probably no reserve power. Can you check with the Builder (company) to see if there is an option for a larger power supply?

i7 7700

yeah that's a good heater in there :)

jokes aside, I don't think Acer will put a horrifying power supply in there. It probably has a PSU that's around Silver or Gold tier in efficiency.
