Not sure where you are seeing £1650 3090s while the 3080Ti's are selling for £2000 for AIB cards, unless you are seeing a used FE being sold that comes with zero warranty, no shops/etailers are selling 3090s for £1650, even the MSRP on AIB 3090s was more for them on release. Apart from the odd one that was meant to be £1500 like the Asus TUF but as we all know Asus raised the MSRP two times after and hardly even sold any at the £1500 price because there was zero stock.
The cheapest 3090 AIB I can find right now is £2000 and cheapest AIB 3080ti £1850, FE cards don't count they are being sold by Nvidia with a fake MSRP to make this generation look cheaper than it really is and they don't/didn't care if they take a hit as most of their GPU Dies are sold to AIBs at a price they can't match the FE price ever (3070Ti FE and 3080Ti FE corrected the FE prices as clearly Nvidia got sick of taking the hit). So only place these prices you are seeing are EBay and unsold bids that right at the end get snipped at a higher price, can't see any recent 3090s sold for that on EBay either. Prices are still silly on all cards and nowhere near MSRP , £1650 is a basic MSRP AIB card when they were released over 9 months ago, so guessing what you have seen is a 3090 FE being bid on at £1650 so far and sells for £1400 from Nvidia so even then that's £250 over MSRP and by time it sells will be even more.
The 3090s last drop didn't take 40 minutes either, first drop vanished in 5 minutes max and then it said out of stock, but what happened as always happens is some customers get declined orders and then they stick them back up for sale later, so what seemed like 40 minutes to you was actually 2 drops at different times in that 40 minutes, second drop they vanished right away, maybe 30 seconds if that, by time you refreshed or added to basket they were gone, same happened with the 3080s too there was a second drop because of cheeky people trying to buy more than one or their payment method got declined, the 3080s again vanished by time you clicked the basket or the link to the page.
If you can find 3090 AIBs for £1650 new from a retailer please let me know we need more of them at work
, we don't want FE cards as they caused us problems and we sold them all and replaced them with blower AIB and AIB 3 fan cards, because we have them in SLI/NVLINK and they whined like crazy the FE or had rattling/grinding fans some of them and over heated easily and throttled, the memory was the big issue for us as the cards have terrible thermal solution for the memory at the back of the cards and our work pushes the GPU and memory to the max. So we avoid the FE cards like the plague now. Cheapest AIB cards right now are £2000 for the 3090s from a retailer with a warranty.
I think some here think they can cause a panic with false information
. Yes prices are coming down but nowhere near the MSRP or the release prices last year in September to December 2020 (based on AIB cards not FE cards). Even the new release FE cards have been price corrected and cost a lot more than they should have compared to original FE cards prices released in September last year. Good example the 3070Ti and 3080Ti are way over priced and soon they will phaseout the 3080 FE and 3090 FE and people will be stuck with them as highend FE cards available to buy. Just a matter of time, they were price corrected as Nvidia was clearly having enough of taking a hit on their fake MSRP.
