Hello, I was hearing alot of gpu bios i didnt know about them, well i dont know anything about them, i got some questions maybe someone can help me, Where can you check their bios info, and when and how do u know when to update them? Or their is no need?
There is really no need to upgrade the BIOS on your card unless you're experiencing some compatibility problems or something like that. You can use a tool like NiBiTor (http://downloads.guru3d.com/download.php?det=1636) for example to modify your BIOS or to just get some more information about your card.
for ur evga 8800 GT, there is a bios update which deals with temperature if ur card is getting too hot.
