Re: Wow!! Major price drop!
He's comparing 2 4870's which are in the same price range as a single GTX280, which to some might be a one option versus another purchase scenario. This is also telling of how well the 4870 X2 will perform, so stop attacking. This is actually rather informative.
The stuttering is probably mostly for the same reasons the 9800X2's stutter. Even if it is GDDR5, you're still stuck with 512 megs of ram and a 256 memory bus, just much faster ram.
