My mistake, my eyes SAW 390 but my brain saw 380. As with the R9 2xx series vs Nvidia, it matter what resolution you'll be gaming at. Not worth the price OR the extra power consumption to me. In reality, as Geofelt said, either card is pretty comparable aside from power consumption. I haven't seen any concusive benchmarks that show the extra 4GB makes any difference for the majority of titles, regardless of resolution.
