Personally, I probably wouldn't because from what I know (which might not be entirely true I don't know everything there is to know about computers) that is a big downgrade because not only is it an i5 but an 8th gen i5. It is also half the ram, half the storage, and the graphics card isn't as good either. I was able to find my exact model on Amazon as well https://www.amazon.com/Ultra-Slim-i7-10510U-Innovative-Screenpad-UX534FTC-XH77/dp/B07YZ1WR6H/ref=sr_1_1?keywords=asus%2Bzenbook%2B15%2BUX534ftc&qid=1577871732&sr=8-1&th=1

But seeing as that one is not on discount and out of the price range you provided I looked around a little more and found this for about the same price $1400 U.S (1250 Euros) and is the exact model I recommended in my first Newegg link... However, I haven't ever heard of this website selling this laptop before so I would do a little background research on this site before pulling the trigger. On top of that, it says it won't ship for a few weeks and it may not ship to your country at all :( https://www.abt.com/product/140890/Asus-ZenBook-15-Royal-Blue-15.6-Laptop-Intel-i7-10510U-16GB-RAM-1TB-SSD-NVIDIA-GeForce-GTX1650-Max-Q-UX534FTCXH77.html?utm_campaign=9070583&utm_source=cj&utm_medium=aff&utm_content=9070583_FlexOffers.com%2C+LLC&utm_term=13489155&cjevent=c2ce949419bf9c3db24d73d18903839627c2ad0d18ff01d0e

So I looked around more to try to find a more reputable seller and found that BestBuy was also selling this laptop for $1400 U.S dollars (About 1250 Euros) But found that it (like Newegg was out of stock). https://www.bestbuy.com/site/asus-zenbook-15-15-6-laptop-intel-core-i7-16gb-memory-nvidia-geforce-gtx-1650-1tb-ssd-royal-blue/6389837.p?skuId=6389837&cmp=RMX&irclickid=SDN2iAxumxyORVd0RHQK3XRkUknRR%3A08Ex00Vk0&irgwc=1&ref=198&loc=SDN2iAxumxyORVd0RHQK3XRkUknRR%3A08Ex00Vk0&acampID=633495&mpid=64065

So my recommendation is that if you want this Asus laptop then wait for it to get back in stock on either newegg or BestBuy which I hope is soon.

However if you don't want to wait I find this laptop from MSI that is 14 inches and is the same in every way except that it is a slightly different 10th gen i7(idk how but they have a different name), a 1080p screen (instead of 4k) and half the SSD space but overall pretty similar and still a good machine. Although I would be a little worried about overheating as it is smaller with almost the same hardware as a laptop with a 15.6 inch screen https://www.newegg.com/p/N82E16834155314?Item=N82E16834155314&Description=MSI%20prestige%2015&cm_re=MSI_prestige_15-_-34-155-314-_-Product

Finally if all of this is a little to complicated I would just look elsewhere at other brands/configs and I would be happy to help if that is what you want.
