CTX-SLPR

Don’t know if you bought the M4000 yet but I poked around for the first time on Facebook Marketplace and noticed there is someone selling a pair of Quadro RTX 4000s for $400 each.  I seriously thought about it but looking into the performance the fact it’s a single slot design makes it run obscenely hot for gaming which is probably 60% of my usage of a card.  However wouldn’t be a bad one for your friend if it’s in the budget.

I'm coming around to your way of thinking reading how the EVGA AIOs are produced in batch lots so a Pascal block/pump would be out of support now and AIOs do wear out. 
 
That sounds like a decent system considering the improvement in architecture in CPUs, don't run CAM so don't know how that scales but then again stuff like that tends to be time in the background while it paths the tool and generates the G-code.  That RAM ought to handle the fun.  Had an M4000 before the P4000 and it was good till I went crazy with trying to make stuff look real and add 100's of fasteners to an assembly.

Here's a slightly updated look at how the RTX Quadros helped with SW19+

Looking over the available stuff I couldn't find a direct comparison with between Pascal and Turing performance with SW19+.  I emailed Puget asking if they had some data on that comparison for the Quadros.  I did find some data on how the 2080 Ti,Titan Xp, and Quadros did and SolidWorks doesn't appear to be one of the applications where NVidia pushed Quadro driver stuff into the Titan line though it does do better than the 2080 Ti according to the GN/TechGage review (https://www.youtube.com/watch?v=gKBLrkZtIVk), just slighly behind the P4000.
 
It looks like a used Titan Xp (or if cheap enough an X Pascal) wouldn't be a bad compromise card for me since a Titan V or an RTX Quadro are out of my reach and the lower SKU RTX Quadros would likely be worse for gaming than my current 1070.

Just because I wanted to close this out, I checked the PS that came out of the case and it’s a SFX unit.  That opens things up quite a bit.
 
Thanks

I guess I should mention that I really don't care about RGB as it lives inside of a computer cabinet anyway.  I have liked my Ripjaws red memory but I hardly have a color theme going, more just a pile of functional parts.
