hey guys I recently just got a Powermac G4 Quicksilver 733mhz for $50. Its got 1.25 gigs of ram and two 40 gig HDs ( I added a second one). The video card is nothing special and I wan the most jacked video card i can possibly load into it. I have found some G4 4x AGP card on ebay that are mac certified that will work but being a person that likes to mod stuff and a person who is going to be an engineer I figured I get me a PC video card and flash the ROM and make it work in my G4. after I get this G4 card I'm gonna get a Sonnet Tech ST G4 1.8ghz.

so what is the best PC 4x AGP card I can flash to work in my mac
