Gigabyte 3D1 - Aside from that, the question as to whether the Gigabyte 3D1 is a worthy purchase leaves us with the same question as purchasing two 6600GTs in SLI - Is it better to get two 6600GTs for your money, or a single 6800GT. From Hexus.net's benchmark results, that seems to vary on what settings you intend to game at -
The 3D1 often seems to have the upper hand in scenarios where raw power is required, but throw anti-aliasing and anisotropic filtering into the mix, especially at high resolutions, and suddenly the 6800GT and particularly the 256MB of dedicated memory for the GPU it offers seems a much more sensible proposition.
MSI GeForce 6600GT PCIe Video Card -
MSI's GeForce 6600GT offering comes in two flavors, the NX6600GT-TD128E, and the NX6600GT-VTD128. The only differences between the two are in price - $187 for the TD128E and $222 for the VTD128, and also in the fact that the VTD128 features VIVO capability while the TD128E doesn't.
nVidia SLI Technology - Introduction and 6800 Ultra Performance - You can complain all day long about the price of a top end SLI setup but
there is no denying that two GeForce 6800 Ultra's in SLI is going to give you the best gaming experience around. This setup isn't for people with a 17" CRT or LCD that can only support 1280x1024. This setup is for people who own 21" CRTs that play at 1600 and above or Wide Screen LCD owners wanting to game at 1920x1200 without having to worry about having to drop to 16-bit or sacrifice a bit of image quality for a smooth frame rate. With an SLI setup you can play with it all turned on and still be smiling.
