Well are you ? Its been talk of the town for a while now, and it looks like itll lift off soon - the ability of having 2 graphics cards working simultaneously to give you a massive boost in graphics performance in my view, has come pretty late - theres been dual cpus, which is a similar sort of thing, which now have been out for a while and I think its time has come, for SLI to be introduced
So will you upgrade? Its exspensive - a mobo will set you back a lot alone - and on top of that, youll need 2 identical graphics cards - pricey I know, but Im just wondering, whos actually gonna do it
