So I finally scraped up enough money to get myself a decent graphics card (I hope), and I have it all installed correctly on my PC, and I can get video through it, but I am confused as to what drivers to install.
It's a Radeon HD 7750 from Gigabyte, and after finding the model number and going through the downloads page at Gigabyte, I ended up with a driver file called "vga_driver_amd_vista(win7)", however, (correct me if I am wrong), my GPU has two DVI outputs and no vga outputs, so why is the file named vga driver?
Also, before inspecting the card manually, I found the PnP number on my computer:

and looked it up on Pci Database, and it returned it as a Nvidia GTX 460: http://www.pcidatabase.com/search.php?device_search_str=0x0E22&device_search=Search
I figured this must be wrong and just looked on the card manually, but then I was checking for windows updates and saw this:

I am extremely confused now, and I do not know which drivers I should install. The GPU says it's Gigabyte, yet Windows and PciDB say to install these other drivers, what should I do?
