Now this one may start a flamewar.... I hope you folks can be restrained enough to not devolve into that, but here goes...
SLI and Crossfire. From what I've read, SLI is out, tried and true, proven to work, but a little iffy on the implementation of things (Profiles, etc). Crossfire isn't out yet or hasn't been out very long (R520 I believe, with the R580 in the wings) and I've not seen much about it. However, what I've seen is that it might not be as fast as the SLI 7800GTX, it's got some better technical merits (SuperAA, Supertile, etc). I'll be honest - I've owned both ATi and nVidia and I prefer ATi - hence why I got the x800.
Say... in a month, what do you think the state of Crossfire will be and do you think it might surpass SLI?
