GeForce GTX 970 or Radeon RX 570 for GPU Accelerated Rendering

I currently own a NVIDIA GTX 570, which works OK with Vegas Pro 14.  Does anyone know which is the better choice for a video card upgrade (see below)?  Is there a significant GPU improvement using Vegas Pro 15 vs 14?  FYI, I have two displays running at 2560 x 1440 (one is rotated).

GIGABYTE GeForce GTX 970 DirectX 12 GV-N970TT-4GD Video Cards

• 1664 CUDA Cores
• PCI Express 3.0 x16
• Twin Turbo Bidirectional air intake fan
• Powered by NVIDIA GeForce GTX 970 GPU
• Integrated with industry's best 4GB GDDR5 memory 256-bit memory interface
• Features 1x Dual-link DVI-I / 1x HDMI / 3x DisplayPort
• Recommended system power supply requirement: 500 Watts (with one 8-pin external power connectors)

ASUS ROG Strix Radeon RX 570 O4G Gaming OC Edition GDDR5 DP HDMI DVI VR Ready AMD Graphics Card (ROG-STRIX-RX570-

O4G-GAMING)

• 4GB 256-Bit GDDR5

Does anyone have even a better choice than the video cards I listed above that cost less than $250.

There should be a significant speed improvement in AVC rendering with the new MAGIX AVC encoder if you have a card that supports NVENC (i.e. The GeForce GTX 970). VCE (AMD's equivalent) may be on the way, but no guarantee and no date yet.

There is probably not a significant increase in preview performance with either card in VP15 compared to VP14, and we're no longer in a situation where AMD is clearly preferred to NVIDIA, like it was in VP11-14. GPU support is in a state of flux, and highly dependent on driver versions. (Short version: I personally don't know which card is best for preview).
