To some extent you cant test on PTR if no beta access. There is a chance the new zones are noticeably more complex than the BfA ones but like, kind of doubt they pushed it that much.
Used RTX 2070, 1080 Ti, maybe some options for a panic sell of 2070S/2080. And at some point there will be sale on the new 2070S, leftover 2080 etc. From AMD side there may be options for RX 5700 XT, especially after Navi 2 announcement in bit more than a month. Waiting for new cards is also an option depending on budget and expected performance level.
For streaming+gaming+boxing you may also need more than 4 cores.
Wait for the 3070 release, your computer can probably handle SL fine even with multiple instances.
After 3070 release, you can either get a 3070 if you’re lucky or at least current options will drop in price considerably.
RX480 can run it fine, although without all high settings depending on resolution… and if you buy RX 5000 GPU you get Shadowlands for free (if the promo is still up):

Although due to Ampere and Navi 2 launches current RX prices are kind of questionable unless they change soon.
Well times change but wow still can be run with mid range graphics but time of low end pc running wow is over logic here is that as technology moves forward so does Blizzard adapt to it.
How much did you pay for yours? £350 quid aint cheap lol - well not in the middle of a second covid crisis and xmas around the corner. Could get a ps5 for that.
