Here are my Passmark scores;
Passmark System Rating= 4262 / CPU= 19625 / 2D= 566 / 3D = 4718 / Mem =1807 / Disk = 6629
System: 2x 2670, 64GB 1866MHz, 256GB Samsung SM951 (via ASUS Hyper M.2 X4 Mini) boot disk, 480GB SanDisk Ultra II, 2TB 7200rpm, 4TB 5900rpm, Quadro K4200, Tesla M2090, Syba 2 Port USB 3.0 and 2 Port SATA III PCIe 2.0 x 4
I understand my memory although rated at 1866MHz is in fact only running at 1600Mhz. I believe this is dependant on my processors only being the E5-2670 and therefor limited to 1600MHz and not the E5 v.2 versions which run at 1866MHz.
Using CrystalDiskMark 5 gives the folowing;
From left to right:- 2TB 7200rpm drive, 480GB SanDisk Ultra II and Samsung M.2 SSD SM951
Similarly, haven't noticed a huge difference in boot up speed but file transfer speed has improved quite a bit.
I picked up the Tesla M2090 very cheaply (since they are older generation cards) but I think it may be throttling the system performance (i.e. using up valuable PCIe lanes). With only the K4200 installed, Solidworks rendered a 5000 x 4000 image in about 7mins 40secs. After installing the Tesla M2090 this increased to 8mins 15secs? I think I will try removing some of the add-in cards (e.g. an additional SATA III card and Tesla M2090 cards) and re-run the benchmarks. I think the Z620 benchmark test you found was mine when I first got the Z620.
