Very Low FPS (melee) [better before PC upgrade]

[na3l]

Hey there Dolphin community,

This is my current PC build

OS: Windows 10 - 64 bit
MOBO: ASRock 970 Extreme4
GPU: GTX 1070
CPU: AMD FX-8350
SSD: OCZ Vector 150 + HDD for media files
RAM: 12 GB DDR3 G.Skill Ripjaw
Monitor: GSYNC Dell S2417DG

I have been playing Super Smash Brothers Melee with Dolphin for a few weeks and was running the game at 60 FPS no problem, with a bunch of other applications running as well. Then I swapped out my GPU and CPU and now melee plays very unstable, with 25 fps max. I am using Dolphin 5.0-321

The components I had in previously were:

GPU: Radeon HD 5770
CPU: AMD Phenom II BLACK X4 945

I didn't change anything in the settings after installing my new components but I have been tinkering with settings in order to correct the issues, including:

Trying DX12 (using DX11 normally)
Trying CPU overclock on/off
Enabling and disabling multi-core use
Changing "speed" setting to 100% and "No Limit"
Setting resolution to Auto vs fixing it at 1080

None of these made any differences and I'm stuck. Any advice would be GREATLY appreciated.
