I thought that's what you meant when you compared 3 cards to a single new one. I can promise you if a 19 year old mouth foamy gamer has a credit card with $5,001 of room on it and that 4090Ti costs $5000 out the door with shipping, that kid is buying that card and Nvidia damn well knows it. Nvidia simply has to balance the cost of segmenting and marketing a new tier of card vs how many mouth foamers will borrow money to get it. You buying one for work is the exception, not the rule. The high Vram makes it like a cheap Quadro or something for certain applications that aren't dependent on specialized drivers.
Nvidia is practically in a monopolistic position in terms of market share. Most gamers simply won't buy AMD. It's not even an option for them, no matter how hard Nvidia continues to ream them each new gen. If gamers want to game, they will pay the higher prices or simply get nothing. I'm hoping Nvidia makes a huge mistake and either delays the 4000 series, prices it way too high, or both. I want to see everyone either buy AMD or a used GPU instead. Charging $1200+ for a 3080Ti when the same card with 2GB less ram cost basically half the price is enough for me to wish for their demise. The 3080 was unavailable, so instead of making more, they added 2GB and doubled the price. This justifies coordinated behavior on the part of gamers so they can act in a collective manner for better valued products.
There should be a consumer's union of sorts that issues recommendations to buy a product based on historical pricing and value, or not buy it. I feel about Nvidia the way I did about Intel when they charged $700 for 6 slow cores or $400 for 4 faster ones for more than a decade. All I wanted was for Intel to burn. They almost seemed to intentionally frustrate and abuse the consumer, as if to punish them for being in the position of eating off their master's plate. The time has come to storm the stables, take the cattle and corn, spill the hot soup in our master's lap before trapping them inside and BURNING THAT PLACE TO THE GROUND!
