The video card looks more like a game card design ( 3D )
I would suggest you find one hooked up to 2 monitors before you buy it.
I have found that many of the game cards do not perform to well in 2D modes
The second monitor image suffers from jag edges in fonts and shake in images
You would be working in 2D most of the time.
when you edit video

When you edit video you will want the max your hardware + Software supports and uses ..
I have 4Gig installed in my new rig.
With 3.5 being used for edit work.
This has dropped my render time to half of what it was in the past
