There's also a HD 3850 512MB version
|- Welcome to the PowerColor World -|
which is interesting as far as performance goes.
Single card vs single card, the 3850 512MB will perform between that of an 8800 GTS, and an 8800 GT

But they're also cheaper than an 8800 GT.
And in crossfire vs SLI, the performance will be roughly the same
Basically, the 8800 GT will perform better if you're using it as a single card.
Though I am liking the crossfire option, considering the cards are not expensive.
You know what? I might even consider a complete AMD Spider platform.
