hmmmmm for this new pc do i go gtx 1660 Super (good value, great performance for a non RTX card, especially for its sub-£250 price - usually goes for around £200) or do I splash out on an RTX card? which will cost around about £300-£400?

@Nine personally I am waiting for the 3060 to be inevitably announced before buying a new card, people speculate it will be around £250.
@gulfie though if rumours are correct that it's coming out mid november, yeah I might wait for the 3060 too come to think of it. :o it's the same price as the 1660 Super thereabouts and will prolly have better specs.
@Nine the 30xx cards are absolute beasts for rendering stuff in Blender which is helping me wait lol
