Couple of other hardware related questions

When you Quad SLI, the speed of all GPU's drops, but Tri-SLI the speed stays at 16x.

Unfortunately most people think oooooh a 4 PCI-e 2.0 slot motherboard, mine will be the most powerful, then they find out its not :P

The best thing with a 4 way, is to have 3 SLI'd and one not, the single one can be used for a 2nd monitor which can be used for everyday normal stuff, while the triple sli can concentrate on gaming.

What i have found is that when people i´ve known to go Quad SLI is that the use dual gpu graphic cards like the 9800GX2 on 2 x PCI-E ports, apparently this way it does not slow down, of course the choice in graphic cards gets very limited then, i think in modern terms aside from the mentioned one, one of the gtx cards is dual gpu cored? dunno havent really installed anything gtx further from 260

Thats a myth.

The bus speed is 16x.

Some Quad-sli actually drop to 4x, others 8x.

No matter if its Dual GPU's or not, the bus speed if quad-sli'd will drop lower than 16x for both GPU's on each card. It doesnt work like 2 dual must mean 2x8 speed.. its still 8 speed

But how does that make sense? why does it slow down?

Lack of bus bandwidth?
