Thank you for your thoughts; they are greatly appreciated.The monitor is a 60hz display, which we wouldn't recommend for gaming nowadays. It will work very well as a secondary screen though.
Depending on your budget we can look at matching a monitor to suit.
But at this point we would be looking at speccing a full system out with you.
Looking at the above, I don't really see any requirements that would warrant 16 cores, you're looking at needing to some fairly top end video editing or other productivity work before you'll see benefit going past the 9800X3D. In terms of being 'no faff', and also holding the title of the best gaming CPU currently available, the 9800X3D would definitely be where I would be looking.
In terms of the overall build, we would just need your budget for the build, and a monitor if you're looking to invest in a new one (I would recommend doing so). If this isn't majorly urgent we can wait to see where the RTX 5070 and RX 9070XT land in terms of price and performance next month too. As stated above the new GPU generation has been disappointing so far.
I suppose I also have tabs open on Edge, along with Discord - and therefore need that extra headroom, especially when playing games like CSII. I was thinking of 14900KS because of its much higher core-count: 8P and 16E.
My machine is used 90% of the time for gaming, but I do like the odd video-editing of videos that I capture via my iPhone that I upload to YouTube.
This led me to think more along the lines of 7950X3D but with the newer 9950X3D, that seems better; depending on price! , but I am conflicted.
Regarding the monitor; I will look into them; do you have any recommendations?
