FX 4100 + RX 470 High bottleneck?

[Nenton]

Hi, i have found an RX 470 at sale, and i think that is a good chance for getting a nice card at a lower price, so.. the problem here is my current build:
FX 4100 @3.9Ghz
GA-880GM-UD2H
16 RAM 1333Mhz
500W 80 White Evga PSU

Is really worth getting the 470 now and upgrade the cpu later? At least i can use the 470 on this until i get money for ryzen?

BTW: My current Gpu is an HD5670 512MB GDDR5, and i want to upgrade to R7 1700 + Gaming k7 + 2x8 Corsair Vengance 3200 Mhz

I wouldn't worry. The bottle neck will be minor and then only in some games. Besides, CPU bottleneck doesn't hurt anything. Just means that it might perform better with a faster CPU. The difference between the HD 5670 and the RX-470 is tremendous. Even with a FX-4100. And the card will be there when you get the Ryzen platform.
You could opt for a less expensive card, but your performance will be less too.

Yeah, i cant hold anymore, playing SFV at Minimum with textures at 40% and playing DS III with an ULTRA LOW graphics mode at 1280x720, i neeeed it, NEEED IT. Oh! and what i should choose? 470 8GB Asus Strix or 570 4GB Aorus? They are at same price on my local hardware store!
BTW: Thanks for answering my questions! You are helping me a lot!

I had a 4GB RX-470 in a Phenom II X4 965 BE (4.1GHz). I could play Doom 2016 @ well over 60 fps using the Vulkan API (1080p) on Ultra. The "newer" RX-570 is basically the same card with some minor tweaks. http://gpu.userbenchmark.com/Compare/AMD-RX-570-vs-AMD-RX-470/3924vs3640
The double VRAM of the 8GB 470 will be the better choice over the 4GB 570.
