I have read the first and last page of this thread.
I saw so many errors it got me quite irritated, one in the guide and one in a reply (although that could have already been answered).
the one in the reply was asking about a monitor with a good refresh rate, around 6ms or under.
6ms is the response time of the monitor, not the refresh rate. the refresh rate is measured in hertz, and is generally around 60hz.
the error in the guide was about MultiGPU technology being only for PCI-E graphics cards.
here's a quote from wikipedia that I read a long, long time ago:
"Scan-Line Interleave (SLI) from 3dfx is a method for linking two (or more) video cards or chips together to produce a single output. It is an application of parallel processing for computer graphics, meant to increase the processing power available for graphics. SLI from 3dfx was introduced in 1998 and used in the Voodoo2 line of graphics accelerators. However, the original Voodoo Graphics card and the VSA 100 were also SLI-capable.
Nvidia Corporation reintroduced the SLI acronym in 2004 as Scalable-Link Interface"
3dfx's technology was meant for igp, pci and agp cards. I remember there is a geforce <6 card which is AGP and is SLIable, although not in the same way that we do it today. You used to have a master and a slave card, which used a daisy chain cable to connect from the vga socket on one card, to the other socket on the other card, and then on to the monitor.
so it would look like this
