I have a spare laptop with 8 GB RAM and SSD (big enough for pruning). Any idea how a Monero GUI node would perform on that? I last tried a Monero node years ago on a server with HDD, and it slowed down the entire server so I never touched it again.
In general, as you already know, a Monero node is demanding.
I am certain that it will work properly, since I 've been running it on a worse machine than yours and it's okey-ish.
Just make sure to pay attention to that post:
