I want to know how far I can safely push my GPU in msi afterburner, give me the numbers baby(if possible). Thanks!
You've not mentioned which aftermarket company that graphics card is from (ASUS, evga, gigabyte etc), there's no telling how far you can OC it, I don't even know what the factory clocks are on that. But it's simple, keep pushing the clocks upwards slowly (say 20mhz) time to time and when it gets too hot running fortnite, stop there.
Do check the fan speeds, turn them up as far as you feel comfortable with, put it to the best balance you can. (Noise / Cooling)
Well what he saying that the amount you could push it probably won't show much of any improvement and because the card is so old it may cause issues and damage the card. Also there are no currently updated drivers for the 4800 series since it so old I'm would bet there are optimizations that have been done for games that you can't take advantage of. Personally I would suggest upgrading your video card to a GT 1030 2GB with GDDR5 (make sure) or up to a 1050ti if you have the extra cash.
A 10% overclock on a great card is optimistic and that’s no great card. Let’s say you average 20fps before overclocking by 10% the absolute best you will see is average of 22fps which isn’t noticeable.
