PCI vs PCI-E

[Charles_35]

I have a Gateway DX4820-03 motherboard. Can I put a PCI-E video card into the motherboard?

Yes, it has a red PCIe slot.

SInce your PSU is only 300W, you might have to change it, too, depending what video card you are planing on using.

I have a 500w psu and a Nvidia 640 graphics card. Can you recommend a good graphics card.

What is the make and model of the PSU?

EVGA 100-W1-500-KR 500W ATX12V / EPS12V 80 PLUS. Everything has been upgraded from the graphic card, thermaltake heatsink/fan, and hard drive. However I have not replaced the processor. I am running windows 10. I am looking at the Nvidia gtx 950 sc graphics card. At this point I don't know if it would be wiser to save the extra money and buy a barebones computer with a better processor.

I like the choice of video card; however, personally I would get a new setup.
