DDR SDRAM on MOBO - What type of AGP memory can my add-in card have? And is the MAX supported limited by BIOS?

Question

...wanting to buy a new video card and wondering about limitations. I have an older board (very stable) and want to better experience my Vista OS.

Answer 1

Do not confuse system RAM on mobo with onboard videoRAM in the graphics card. They work independently and need not be the same.

If you want fast graphics for games, get a graphics card w/ ddr3 videoRAM. BIOS limitation would be on AGP bus. Very old mobo support 2X AGP only, newer ones support 8X AGP. It is pointless to buy a fast and expensive AGP card if you only have 2X AGP.

Another limitation is power supply. Fast and powerful cards require a bigger power supply.
