PCI = 533 MB/s max.
ISA = 8 MB/s max.
So 525MB/s faster.
If you look at your manual, you will see there are no ISA slots on this board. 2- pci-e 16x 2- pci-e x1 1- pci
The PCI slot is faster. Offer mayor speed because the PCI use more faster BUSes and new architectures. The PCI EXPRESS is the newest version of the PCI architecture.
PCI, AGP, and ISA are types of expansion bus slots. These slots allow you to attach internal peripherals such as video cards, hard drive controllers, modems, tuner cards, and other things.
These slots are faster than the older PCI slots, making them more suitable for high-performance video cards.
An ISA slot may be used to add a video card, a network card, or an extra serial port. By the end of the twentieth century, ISA ports were beginning to be replaced by faster PCI and AGP slots. Now, most computers only support PCI and AGP expansion cards.
Physically, PCI slots are light-colored (usually white) and much smaller than the black ISA slots. Computationally, PCI technology was designed to automatically assign address information to the hardware plugged into it. This was a vast improvement over ISA technology which required a considerable amount of manual configuration.
The original IBM compatible parts used an 8-bit ISA slot. After that, they moved to a 16-bit ISA slot. There were other things like a VESA slot that didn't last for long. Then there were PCI slots (not express), and AGP was a faster video card slot standard. Then PCI-express replaced both PCI and AGP.
PCI has several advantages over ISA, that make it a better choice for most devices.1. PCI is several times faster. ISA is an 8/16-bit interface that runs on an 8 MHz bus. PCI is a 32/64 bit interface that runs on a 33 or 66 MHz bis. Thus more data is able to transfer to and from the PCI bus.2. PCI was built with Plug 'n' Play support in mind. No special configuration is needed when you install PCI cards. When installing ISA cards, you will often have to configure jumpers on them to specify an interrupt and DMA channel, and many cards can be incompatible with each other.3. ISA is all but absent from modern computers. One of the requirements for a computer to bear the "Made for Windows 2000" sticker was the removal of the ISA bus. So there have not been any major ISA motherboard vendors in 10 years.

AGP slots were used as a faster interface for a graphics card prior to the creation of PCI-E.

They were known as an "expansion bus". So-called because the expansion cards with edge connectors, plugged directy into the bus board. (Today we would call it a motherboard) There were 3 bus standards: Industry Standard Architecture (ISA) Micro Channel Architecture (MCA) Extended Industry Standard (EISA) I hope that helps.
