Whilst I'm not happy about the 4090 price there is nowt I can do about it. You pays your money, you makes your choice. My money my spends.
What I don't understand though is some of the folk complaing, have sigs with £500-£700 mobo's, £500-£700 CPU's, very expensive RAM (low latency DDR4), Top end PSU's ~£250+, top end NVME's etc. But cant stretch to the most important part of the system, the component that will make the most difference. If you didnt spend so much on the other high end stuff that will make a few % difference and spend it on the component that makes the most when gaming - then I don't really get it.
All those components have risen massively and no one is moaning about those.
OK, the 4090 is comparatively £3-400 more than the 3090 MSRP. But seeing what 3090's are now EOL, this card is plenty for non 4k, VR, multi panel sim setups, as is the 3080ti and 3090ti. All within near as makes no difference gaming wise.
Match your GPU to your resolution and hz you are trying to drive. You dont need a 4090 unless you are 5m pixels or greater with high hz panel. Anything less - a waste.
High end VR setups are the same £ as a 4090, racing sim setups, cockpit setups can be in the 10's of £1000's and everything in between. Normal, 1440p (even 144hz) a 4090 is a waste. Unless you are driving 5m+ pixels get a 3090 or 6900XT..... they are still very capable cards even at 4k. Just not as good as a 4090 - which is made for gamers that have very high end setups.
The PC MASTER master race.
