Considering GPU Upgrade

I'm considering about having upgrade my GPU, in order to explore DaVinci Resolve, while still keeping the Sony Vegas Pro 13 running. So far I'm still working with FullHD 1080 projects (4K UHD is still long time).

Right now my System 1 spec is:
OS: Windows Pro 10
RAM: 12 GB
Processor: Intel(R) Core(TM) i7 CPU 950 @ 3.07GHz (Intel Motherboard DX58SO2)
Video Card: Sapphire ATI Radeon HD5750 Series (Catalyst 15.11) Memory 1GB

Reading on this blogpost and Configuration Guide PDF from BMD's site, I'm lack with GPU Memory, and recommended for 4GB video card.

Based on this availability list, my most budget choice for upgrade is:
XFX Radeon R7 370 4GB DDR5 Dual Fan - R7-370P-4DFS, or
XFX Radeon R9 380X 4GB DDR5 Dual Fan - R9-380X-4DFS

But, the issue I'm going to face, my Radeon R7 or R9 series is PCIe 3, while my motherboard is still PCIe 2, as noted by my computer builder, but reading other blog, the physical interface is still compatible, and the 'bottleneck' possible issue won't be felt instantly.

Also, by upgrading to this new card, according to this article, Mainconcept AVC encoding won't be able to use the GPU anymore, but there's still benefit on from it, but how far?

Anyone to those using R9 card can share their experience?
Is my 'old' motherboard going to be a big issue for having newer Radeon R7 or R9 video card ?

Looking forward to hear your thoughts...

If you are not ready to upgrade your motherboard, then buying a GPU that you won't fully benefit from because you motherboard is only PCIe 2 is not a bad idea. You will see some boost now, and more of a boost when you eventually upgrade too a newer PCIe 3 motherboard.

It makes no sense to buy a GPU that matches your current out of date motherboard. Always upgrade to the latest technology so that over time, everything gets updates to better technology as you replace components.

Go for the Radeon R9 380X!

The R9 390X with the 8GB works fine with Resolve, also for UHD footage. And it works fine with Vegas too. So that is a great choice I think.
