As the 30 series cards have been coming back in stock and dropping in price, the temptation to just get one while I can has been steadily increasing and I finally reached my breaking point. This one came back in stock priced at basically the exact amount of money I had saved up. I couldn't resist.
Plus, I had sort of given up hope of being able to get a white GPU to fit the rest of my PC so I'm really happy about that. The rumored power draw of the 40 series also has me nervous about my 850W PSU and, again, I'm not sure I'd be able to find a replacement that fits the white theme of my PC.
I'll probably regret it a little when they announce the 40 series (depending on what they announce) but since I won't be going beyond 1440p/144hz for the foreseeable future a 3080 should be plenty for my needs.
