We know it'd make more sense to just spend more money on a really fast card, but--two video cards! Given that you can definitely get two 3850s for $300, it seems like a reasonable upgrade option, even though I normally rail pretty hard against mid-range multi-GPU configurations. The main weakness of the 3850 is its clean performance drop when anti-aliasing is enabled. Without that, it really does scream. Will an extra $150 give it that 4xAA shine?
