Costco is currently running a limited sale on one XPS 15 9570 SKU. The machine comes with an Intel Core i7 Coffee Lake processor, an NVIDIA GeForce GTX 1050 Ti discrete GPU and 32 GB RAM. Better still, the device has a 4K touchscreen display and a 1 TB SSD too. The SKU usually costs US$2,299.99, but the sale brings it down to US$1,799.99.

This more or less brings it in line with what you would get if you added your own memory and SSD -- but you can add a Samsung EVO which has much better performance than the one that comes with the XPS
