Thank you very much for the reply. If you have at least 3 of both (PCIe-PCI), it would be ideal.
I know of no such motherboard. As I noted, PCI is very old and is almost completely phased out. IF you can find a motherboard that supports PCI anymore, most likely it will only have 1 PCI slot.
Note the i7-7770 uses the LGA1151 CPU socket. That means you MUST buy a motherboard with the 1151 socket to use that CPU. As seen
here, Newegg sells 68 ATX boards with the 1151 socket but none (that I see) have even 1 PCI slot.
I have the video on the motherboard which is the Intel® HD Graphics 630. What cheap video card would be better than the one that already comes with the computer? Thank you very much. Greetings.
What motherboard? Understand the Intel 630 is really a pretty good solution for integrated graphics, as seen
here. Without you stating a budget, I don't think you are going to find a "cheap" video card that beats the 630.
What is your goal here? If you are looking to improve performance, maybe you should look at adding more RAM. Or going SSD. Regardless what you do, going back to a PCI card is likely to degrade performance.
