Gigabyte 865 or 845 ? i need to install a Gforce card

[camelNotation]

Hi . I'm using a Gigabyte p4 titan , it's GA-81E2004 motherboard .
I want to buy a 64 mb gforce fx graphics card but i'm not sure if my motherboard's is going to be compatible with the card or not .
I've called up a shop and they were asking me if it was Gigabyte 865 or Gigabyte 845 . I've lost my motherboard manual and all I have is the motherboard box and a precedure for installing the motherboard .
Is there any way for me to know whether it's 865 or 845 other than that of looking at the manual ?

Try downloading Everest Home Edition, click on computer, and this will identify most everything from your mobo to your CPU and chipset.

Either board will support an AGP8X video card. An i845 chipset board should have an AGP4X slot, which should be fine.

Even so, make sure you can get a guarantee that the card you're buying will work in your motherboard.

Everest says that the supported agp speeds are 1x , 2x and 4x .

Current agp speed : 4x .
I'll try and post the result here . Now I understand what they meant by 845 !

okay i've bought octek's tadeon 7000 series 64mb . however , no matter how high i set my desktop gamma / brightness settings to be , the in-game gamma level is always horrible and too dark . Should I try to download a new driver from the internet ? I had one driver with the cd .
