Graphics cards can the MSi PM8M-V more specificly the P4M800Pro-823-6A7L6M4AC-00 run an ATi radeon X1650 pro DDR2 graphics card? and are its PCi ports, standard or express?

Hi noxiney, you're MSI motherboard does have 1 opened AGP 8x4x slot. You can install & run the ATI Radeon X1650 PRO AGP. You can not run PCI-Express because there are no PCI-E slots on the board. There are PCI (White in color) on the board but the AGP slot is much faster than the PCI (White in color slots). The manual states the AGP card can only support 1.5volt video cards & not 3.3volt AGP cards. (Keep this in mind when looking for an AGP card).
Below is a link to a bunch of AGP 8x4x video cards. One or two include DDR2 memory. Carefull where you buy. Check the warranty. (Longer is better). The first one on the list would be compatible. Its not DDR2 but it does have 512MB of memory.

Just remember, if the card can run both 8x & 4x it should support the 1.5volt needed to function on the MB.

Enjoy!
