So far, it's a blast!! Plays Bioshock + Crysis max graphics smoothly. It's very well worth it. Also, the AlienFX console for power + lighting settings is very good, no complaints there! Battery is good for what it powers. It looks great too.
The only cons are that it runs hotter than most but thats to be explected with sli. Also its a bit heavy, more of a portable desktop than a laptop.
Overall, i love it!
