If you're gaming at 1920 x 1200, the HD 5770 is the card I would recommend in a heartbeat, especially if you want to protect yourself a little bit for future titles. It offers us consistent performance at 1920 x 1200 with the detail level set high.
As always, though, we appreciate some extra performance. Last year we saw MSI attach the GT 240 from NVIDIA with its Afterburner software. Outside of just giving us normal abilities like overclocking the core and memory, it also gave us a chance to increase the voltage on the core. What this ultimately meant was that we could achieve an ever higher core clock.
