I want to make a major upgrade between the two. I currently have an eVGA 7800GT and AMD Athlon 64 3500+. If I go sli, does the video card have the be exactly the same? Only the recertifed version of it is sold on newegg, and it has a different memory clock. So, if that cancels out sli, then I will for sure go dual core.

NVIDIA’s Scalable Link Interface (SLI) is based on the simple principle of symmetric distribution of load, meaning that the architecture depends on (and will only really work) if both GPUs get the exact same load as one another. The nature of NVIDIA’s SLI indicates that odd combinations such as cards with different clock speeds or GPU feature sets (e.g. 16-pipes + 8 pipes) will not work; NVIDIA’s driver will run all cards at the lowest common clock speed, but there’s nothing you can do about trying to get different GPUs to work in SLI mode, the driver simply won’t let you enable the option.

Thanks, that really makes my decision a whole lot easier.
