Upgrade Advice? (About 400$ Budget)

I bought my first gaming computer last year, and am looking to upgrade the Graphics Card from a GT 610 to the GTX 1050 Ti (FTW), which runs about $159.99 on Amazon.

My problem is I'm not really all that computer savvy, so I'd really love to get some advice on what else I might need to upgrade along the way. I've tried researching it but it just ends up giving me lots of mixed reviews and opinions. I've had a few that tell me I won't need to upgrade at all, and a few that tell me I'll need to upgrade practically every part. So I thought it best to finally just give out my specs and ask someone whose probably more trustworthy than random google results.

Here are my current specs;

GeForce GT 610
MSI 760GMA-P34(FX)
AMD FX-4300 Quad-Core
8GB RAM
1 TB Hard Drive
450 Watt Power Supply

Hoping this information is enough. I don't have a very big budget... $400 is probably as high as I could go, but I'd really like if I could keep it below that mark if at all possible. Thank you all in advance for the help!

With that budget it would make sense to get an i3 CPU, DDR3 motherboard and a new GPU.

I'd go with an i3 6100, a DDR3 motherboard (ASUS B150M-K D3 LGA 1151), and an RX 480 in place of the GTX 1050 Ti, assuming your PSU is halfway decent. Reuse the remaining PC parts. Otherwise, go above $400 to add a decent PSU.

If I were to buy the above at my regular stop (newegg.com), it would cost $380.

Keep the RAM, PSU and HDD

Wait for Ryzen 5

I'd go with an i7 CPU. Reviews and information on that CPU and other suggestions can be found here - Https://www.gamewire.org/pc-gaming/best-cpus-for-gaming/

For graphics, I'd do the Radeon RD 460 or you can take a look at the others here. https://www.gamewire.org/pc-gaming/best-budget-graphics-card/

Hope this helps!
