For the price they are very outdated. You can make a PC with 3-4 times the performance of these in round about the same price. I'm not over exaggerating by saying 3-4 times, I mean literally 3-4 times.
A SAPPHIRE Nitro+ 8GB RX 480 VR ready card is 36,000 in the market right now and its price is going to fall since these are introductory prices since its new. The card in your PC is 3 years old and gives 40 FPS in BF1 not even at 1080 but at laptop resolution so its struggling to run a current gen game, RX 480 can give more than 40 FPS in 1440p at BF1 with half decent hardware behind it. You don't need water cooling with these modern cards because they aren't being pushed to shreds to run games and because of their improved efficiency. They have so much power that you can tune them down and still enjoy +60fps on current gen games. If you do push them you can get 70-100fps at 1080 in games like BF1 at ULTRA and if we run them at your laptop res then you can get +100fps.
Your CPU is good enough but still lets improve that too. You can buy a 6th Gen i5 for 21k-28k. That's the two most expensive part of the build done.
Power supply+Chassis combo needed for this costs 4-6k. Your PC is missing a hard drive while you can buy an SSD+1Tb hybrid drive for 8k or just a 1tb hard drive for 5k. 8GB kingston 5.5k ram lets go with DDR4 since its not 2013. Heck lets add a GIGABYTE DDR4 motherboard for 6k.
I went overboard with this but you can make this type of PC for 60-80k and it will easily play next gen games too so its future proof. I didn't even consider discounts or actual market prices of most parts and took the high prices of galaxy for most of them.
So not sure why you are selling this for so high. It will struggle to run even current gen games let alone be future proof. 65k is a lot of money with which you can make a great PC. If you bought local and assembled it, you'd make one 3-4 times better than this for roundabout that money.
Its good for games released before this gen but thats about it. Other than that my laptop has better performance than this.
My advise to you would be to buy local and assemble rather than importing. You can sell better PCs and users wont complain for years. I think you overpaid by a lot for these which is not your fault it must be shipping duty. More importantly Australia is one of the worst places on earth to buy Software or Hardware, the prices we pay in Pakistan are cheaper. The prices in US, UK, Middle East are nearly always cheaper than what they are in Australia even if you just buy it and keep the product in Australia without shipping it to Pakistan. Just google it and you will see Australians have to pay ridicolous prices, they will be complaining on every website about it. Even the card I mentioned above is down to 36k in Pakistani market but in Australia its floating at 40k Pakistani rupees. Now think about buying it from there and then importing it to Pakistan, this will explain it I think.
You can sell these to people who aren't aware of market prices but anyone who does research wont buy it.
Still good luck but its going to be difficult to sell these.
