This is getting a little bewildering?
Just re-fitted the Tesla M2090 GPU and Syba SATA III PCIe cards, re-booted the computer then ran a couple of tests.
PassMark now says;
Passmark System Rating= 4336/ CPU= 19594 / 2D= 569 / 3D = 4592 / Mem =1841 / Disk = 7892
Then on CrystalDiskMark 5
What appears to be a very minor difference in transfer speed of the M.2 SSD with the Tesla and Syba cards back in?
Although not related to this thread, I just wanted to share this information since you mentioned you were interested in rendering in your post. Rendering a more detailed model in SolidWorks at 5000 x 4000 resolution without the Tesla card installed took 24m 29s (ran this test just after my previous post), with the card back in it took 24m 10s, so no noticable improvement in real terms.Would be very interested to hear how you get on with the planned Quadro M2000 you mentioned in your post? My son is currently at university studying for a degree in 3D modelling and computer animation so I'm trying to build a decent rendering machine for using with PremierPro, Maya, etc. Looking for ways to boost the K4200 performance. All ideas welcome. Time to start searching the forum.
FYI, rendered image, 5000 x 4000 pixel resolution, (modelled by myself using SolidWorks 2016);
