Ok, everyone is talking about SLI and its advantages... one of which is the scalability of the new technology. To be able to buy one SLI capable videocard now and then add a second one later on (when you've got enough money to buy another one), thus "doubling" your performance is one of the nice features offered by the SLI technology. However there is one big question: How well is the scalability implemented? Everyone is talking how good it is, but they are missing the key points.
