I think SLI won't matter so much to future of computing. But i really hope dual core cpu's get adopted quick and good software support. I seen the prices of dual cores to be reasonable if you build your own computers. But i seen prebuilt systems sell at outrageous prices. SLI will be here to stay but like Reichfuher saids its only for enthusiasts geared people. The same people who buy top end cards are the ones who have SLI setups.
