Hi there
Not sure what we are allowed to say or not say been a reseller.
However the 4090 is very much CPU bottleneck in anything below 4k, infact even 4k does see a performance boost with best CPU's and in our testing 7950X and 13900K certainly gave the card yet more ooomph with CPUs overclocked as it seems to love high frequency CPU clocks, it is a serious piece of kit and is really only ideal for those sporting the very best CPU's and ideally overclocking the CPU's to truly get the best from a 4090.
The best is always expensive, that is life, NVIDIA do a whole range of GPU's that will play games well from £300 at HD, want to max out 4k its going to cost more.
We cannot post our review by 8 Pack until tomorrow but that is with a 6GHz 7950X which truly lets a 4090 properly stretch its legs.
