All good points! But it's 14 years old, which is like 150 in computer years. The HD has gotten very slow. It takes 5 mins to boot up. There's no point in upgrading the OS on it. Given how slow it is now, it would take hours to even install the GoG version of Oblivion on it; Days to install Win 11. Yet it plays Oblivion, FO3, and FNV just fine.
I have been putting off getting a new one until this one dies or I want to play a new game beyond Fallout New Vegas (2010 I think). Even FO4 is too much for it. Time to upgrade.
