What's up friends!.. well I want you to guide me on a GPU that I want to acquire, in fact I revived this PC by changing the power supply, the Intel processor (it had core duo and I already updated it to i5-2400) I added the 8gRam (two 4G ram) and I recently got a 2G DDR3 Nvidia Quadro k620 GPU.

now the question is if this PC I have can support a 4G DDR4 GT 1030 GPU

this one for example...

or this PC only supports 2G... 

I would greatly appreciate your knowledge and help.
