OK im seriously looking into upgrading my PC GPU and i need some advice here, budget is not a huge issue but im not about to spend 4K$ on a GPU to play in 8K480FPS, and it wouldn't make sense with this PC.
I just want to improve my 5y old PC to maximise the performance out of it, in the future I may replace the whole RIG.

Here's the specs.

Operating System
Windows 10 Pro 64-bit
CPU
Intel Core i3 4170 @ 3.70GHz 32 °C
Haswell 22nm Technology
RAM
16,0GB Dual-Channel DDR3 @ 798MHz (11-11-11-28)
Motherboard
ASUSTeK COMPUTER INC. B85M-K (SOCKET 1150) 121 °C
Graphics
LG FULL HD ([email protected])
MX279 ([email protected])
Intel HD Graphics 4400 (ASUStek Computer Inc)
1023MB NVIDIA GeForce GTX 750 (ASUStek Computer Inc) 27 °C
ForceWare version: 416.34
SLI Disabled
Storage
7452GB Seagate ST8000VN0022-2EL112 (SATA ) 31 °C
447GB SanDisk SSD PLUS 480 GB (SATA (SSD)) 20 °C
Optical Drives
ATAPI iHAS124 F

Realtek High Definition Audio

Don't mind the MO cooking, it's a busted sensor.
I was thinking about getting Radeon RX 560-570 as they're fairly cheap but the issue is the PSU, it has that 6pin GPU power cable but the PSU itself is only 450wat, can't tell the brand as I would have to take it apart, the sticker is on the top of it.
Alternately I was thinking about the Geforce GTX 1650 since it doesn't require external power, thoughts, advice?

If you want your specs lasting at top potential longer, consider AMD.
Upgrading processors across generations gets expensive with intel, and their processors' performance seriously tanked from all the various security mitigations. The gpus you considered could be bottlenecked from the i3.

Honestly I'm considering going full AMD for the next pc I either build or buy, but for now I want to get the most out of this one.
As for the i3 I'm considering replacing it with an i7 4770 or something similar.
As for the GPU I'm considering GeForce GTX 1650 super.

Question to experts here, is there a point to install an outake fan there?
On the back of the case facing the cooler, originally there was one when I had the stock smaller front facing cooler, but seeing as the new cooler blows the air that way plus the PSU sucking air from that area I don't see a point.
Plus the outake case fan would be almost touching the cooler, sucking the air from the fins directly.

Ps.
Sorry if it looks dirty, I'm in the process of amateur cleaning it via cloth and canned air.

More airflow is always better, so long as you respect the airflow direction within the case. You don't want fans opposing one another.

Keep in mind, you don't really have to install the rear fan inside the case. It will work just fine on the outside of the case so long as you bend the mesh inward. This might make the case look ugly, but as it's the rear of the case, it's not a big deal.
