You could build a more gaming specific PC for cheaper, with much better spec than the Alienware prebuilt PCs.
A 5800x/3060Ti combo with 32 GB ram and 512gb SSD for £2000 is damn terrible (extortionate)

Build your own, watch a few Youtube tutorials, and its super easy and rewarding to put the parts together. Use something like PC partpicker to get an overview of the parts you want, and use the price history to check if youre getting a good deal for a part. If I can build a PC, then anyone can (serious).
I put this PC together in like 3-4 mins, you could do more research on to choose a motherboard, CPU, RAM etc, but the 3600mhz (XMP) is perfect for the 5600x.

You could find the parts for much cheaper, on sale, and this doesnt include the £649 GPU price. The overall cost of this PC should be ~£1500 (if you pick the items that go on sale often for cheap and pick the rest up at MSRP). £2-5 for a windows 10 activation key saves you £95 for the OS and this shits all over the Alienware PC.
