There are plenty of lanes on both the Z620 and Z840 but you need to use a riser to fit the 3rd card. It’s perfectly practical if you don’t mid open cases but is better if you customise an outer case to manage dust and maximise airflow.
I picked up my Z workstations for well under £1k each and specifically went for E5-2670 CPU’s. These are relatively old but they run at 3.4 Ghz single core and all 32 threads run at 3.1 Ghz. They’ve provided fantastic value, and reasonable performance even though they’re not Intel’s latest and greatest. I’m happy to purchase the best of previous generation hardware if I know where the workstations were previously used. I advocate self builds too with the E5-2670’s seeing as you can still pick up a matched pair for under $200 - this is a good guide to the build. http://www.techspot.com/review/1155-affordable-dual-xeon-pc/ <http://www.techspot.com/review/1155-affordable-dual-xeon-pc/> Buying second hand kit or engaging in self builds isn’t for everybody hence my recommendation of leasing, but for those that don’t mind a little risk you can put a mini farm together as reasonable cost. > On 6 Jun 2017, at 19:25, Olivier Jeannel <[email protected]> wrote: > I mean the 840 could hold max 2gpus > > 2017-06-06 20:24 GMT+02:00 Olivier Jeannel <[email protected] > <mailto:[email protected]>>: > I was told the 820 can hold max 2GPUs.
