Regarding your MSI K8N NEO2-Platinum (MS7025) Motherboard, it should have one AGP (Accelerated Graphics Port) 1.5V 4X/8X slot and an nVIDIA® nForce3 Ultra Chipset. There are a few links below I think will greatly help you.
Sincerely,

Connectivity - AGP interfaceSupports AGP3.0 - 0.8 V signaling for 8× and 4× with Fast Writes data transfers
Supports AGP2.0 - 1.5 V signaling for 4×, 2×, and 1× modes with 4× and 2× Fast Writes data transfers
Supports graphics address remapping table (GART) features
The AGP3.0 8× 533 MT/s (million transfers per second) interface provides the user with the ability to upgrade the external graphics card, thus avoiding obsolescence. An external AGP add-in card achieves higher performance than it would on existing platforms.
AGP interface is backward compatible with the AGP2.0 specification.

And last, but not least YES!!, there is a WIKI page on the AGP.

As of 2009 [update], few new motherboards feature AGP slots. No new motherboard chipsets are equipped with AGP support, but motherboards continue to be produced with older chipsets that have AGP support. PCI Express allows for higher data transfer rates, has more robust full-duplex support, and also supports other devices.
