Awesome 5080 variant - I bought this after selling my 5090 and it’s been a great performer. One thing I didn’t realize before purchasing is the size of this GPU. It is enormous compared to the founders edition, so make sure you have a case that can accommodate a 4 slot card. Performance wise it is very good, I’m still playing my favorite AAA games at 4k without any issues. This is a premium card with a premium price but you will not be disappointed.

Power house! - Upgraded from a 4070ti and was on the fence between a 5070ti and a 5080. Decided to go with the 5080 cause why not lol. Absolutely no regrets, it is a beast of a card all around.

Excellent card - Runs quiet, work extremely well and is everything you would expect from a flagahip card. It is much thicker so i had to modify my case because the fans were up against the glass so ensure you measure for dimension s. It makes my former evga 3090 look like a tiny card. Wish it was a little less expensive but that what we have to deal with the increasing cost of electronics and memory is getting bad.
