PC improve acer tc-705?

I have an acer tc-705 intel core 4406 and would like to improve in max 100 euro for now should not be an ultra pc I just want to be able to play fluently with medium settings fortnite please help me I despair of the pc.

For the others, specs

Intel® Core i5-4460 4 x 3.20GHz 6MB cache (4 cores / 4 threads) and TurboCore up to 3.30GHz
Intel® H81 Express Chipset

NVIDIA Geforce G705 (1GB)

2 x 4GB RAM DDR3 (1600MHz)

1000GB SATA HDD (7200rpm)

If you only want to spend up to 100 euro, then the graphics card would be the best thing here (buy new)

Thank you for the answer 😀

If there was still a question 😅 fits the graphics card in each pc.

No, but there's no graphics card that fits into any PC.
