If the GT1030 appeals then you could save even more and get the XC-885.
You dont need Optane its a fad, your saving almost £300 so could update the GPU and PSU yourself and still be cheaper
You didnt say, the gt 1030 is not comparable as awful, optane is missing, power supply is only 300 watts and the case is far worse quality with poor airflow so not worth it
I told you the model TC-885 comes with GT1030 2GB GPU and after 10% topcash would be under £500
Which model. There is one without gpu?
