The wife doesn't usually have a say on what I spend on my hobbies like what she spends on her stuff is none of my business. However for this particular purchase I just run it by her and she scoffed but also gave the green light. We have no issues with the mortgage and I'm not putting more into it until rates come down (a rate cut next month would be hugely welcome), no kids either, we don't go out places and spend money (take away every friday doesn't count), no other outstanding debts besides the partial finance I have on the car (car loans I would assume are pretty normal), the emergency bathroom renovation last year is done and paid for, savings in the bank. You're right though. My head says it's irresponsible but it's also my hobby. She said I work hard and after a shit couple years I could do with splurging on something I enjoy doing.
I worked it out I average 28 hours a week on the computer. That's 2-4 hours most weeknights and weekend sessions. I'm roughly 2 years between graphics cards. Calculator says thats 2912 hours, and if I were round up new graphics card price to $5500 for worst case scenario or allow for not using it as much that's $1.88 an hour. I think that's a fair price for my hobby.

. If I had have bothered with another car in the 5 figures would have been big dent in savings, and probably not getting stuff I'm getting now. TLDR, those people can FRO.
