Hello, I am not real familiar with computer hardware.  I am looking to purchase a new powerful computer to use when creating large scenes with great detail in iClone and also detailed CC3.  I want something that will handle 1 to 2 gb files.  I need quick rendering speeds and something that will not bog down with these size files.  I don't know whether to get a laptop or desktop.  I do not need monitors.  Flexibility of the computer is not an issue either.  What I get confused about is all the NVIDIA options.  I do not know anything about NVIDIA.  So do I go with  RTX 30 series and if so what is the difference between 3060. 3070. 3090?  Which would you recommend?  Do I need 16 or 32 RAM?  Would you suggest an i9 or will i7 be okay?  Some say quad core.  Is that the best way to go?  Thank you so much for your gracious help untangling this madness for me.  Debbie
