What graphics card does the i5 2400 have and is it better than or equal to: NVIDIA GeForce GTX 670 / GeForce GTX 1650 or Radeon HD 7950. And can it connect to 5hz and 2.4ghz WiFi?
There is no "graphics card" . The i5-2400 has HD 2000 graphics included with the processor.
No, nvida and amd will kick its butt, always and forever.
It has nothing to do with wifi. Graphics are graphics, wifi is wifi, and they are not related.
And, the processor and graphics are unsupported on Windows 10.
And, you have already asked this question about graphics and WiFi.
