Hmm, well if you can wait on the 3080 you can just build it yourself for cheaper. But, to answer your question, yes, Alienware pcs have been proven multiple times to be the worst

You could obviously change the gpu and case for better airflow and maybe use a 5000 series ryzen cpu (prices are US btw)
so you could easily max out your budget with and 850 watt from corsair thats 129.99 just in case you want to overclock but if you just wanna give your cpu/gpu a little headroom to boost on their own go for any 550-650 watt with at least and 80+ gold rating
