Im looking at getting a dual Headed video card and these ones came up: Matrox AGP Millenium G450 32MB Dual Head Graphics Card, DDR-Ram, OEM and the Matrox AGP Millenium G450 16MB Dual Head Graphics Card, DDR-Ram, OEM. i dont think the cards are designed for speed, but id be looking at the 32Mb model becasue thats what i have with my current card. The G550 32MB one is here. the of cource theres this 3DLabs Wildcat VP990PRO 512MB 256bit DDR with 512MB memory!! or 3DLabs Wildcat IV 7210 128+256MB DDR with 384mb total memory! Madness!
