This is very close to the other desktop just a different graphics card. It has probably a 300 watt psu. In theory you could get this and upgrade the graphics card and the psu to like 500w later. This probably has ddr4 and the other has better ddr5
The other desktop is:
DELL XPS 8950 Desktop, Intel I7-12700, 32GB DDR5, 512GB SSD + 1TB HDD, RADEON RX 6700 XT, WINDOWS 10 HOME - BLACK
Note that Dell has been using proprietary 12VO power supplies since 4th gen, sometimes with proprietary sizing too. Going 12VO is more efficient and it’ll perform fine just as it’s designed – but anyone considering this with the intention of upgrading needs to do their homework first.
(Note that I am not staff. I just volunteer to help out on the forums.)
I’d probably pass on this, pervious gen gpus will likely drop further as more of the 40xx come out. Couple months ago paid $100 more for enssentially this package in a new Lenovo with a 3060 and 500w psu.
