The 7 year old Intel Xeon E5-1650 is a server processor that was built for a high amount of RAM and management of multiply external user access. But it was not built for video editing and has no integrated video graphic acceleration
Bogart 7
minimum system specifications request an active Intel HD graphic from i5/i7 processors of the 4th generation or higher since 2014.
Adding an NVidia 1050/1060/1080 with NVENC support may speed up Arabesk Blu-ray encoding and H.265/HEVC encoding, but will not add Intel HD Graphic for smoother playback and other hardware acceleration.
The first Casablanca-4 systems came three years after the Xeon E5-1650 with an i7-4790 CPU and
integrated video acceleration hardware.
As for the 32 / 64 bit .... BogartSE is a 32 Bit application, able to address ~ 4GB of RAM. To address more RAM - a 64 Bit software would be needed. But since BogartSE's roots go back to 1997 and an Amiga OS with just 16 MB RAM, the code is highly optimized. BogartSE uses just about 0,5 GB of RAM when rendering video effects with 2x UHD 50p videostreams. So there is no need for BogartESE to double it's code, just to run in 64 Bit mode.
