At the top is a single x1 PCI Express slot, then a x16 PCI-E graphics slot, and then an AGP 3.0 slot with retention device. Below that are three regular PCI slots. MSI has realised that every PCI Express motherboard will only have two or three PCI slots, and that leaves a fair chunk of system resources free for what it terms an Accelerated Graphics Riser, or AGR. The AGR is effectively identical to an AGP 3.0 slot except that it has a significantly slower connection speed than AGP, so even though MSI has published a list of compatible graphics cards which includes a WinFast 6800GT and ATi Radeon 9700, it's only part of the story.
