Summary: It's not a GTX-690Ti, but it definitely screams. Moreover it runs very quietly and doesn't generate a lot of heat (my computer is on the floor just beneath the A/C thermostat...and moving either just isn't an option). For the price, this board is a solid choice for folks into gamesmanship more than specsmanship.
Summary: I'm a flight simmer - FSX on Win 7. I have a quad core i7 -920 CPU @ 2.8 GHz. I have some gadgets on the side of my 24 inch Wide Screen 1900 x 1200 monitor that I use to monitor various system parameters. The CPU maxes out before this GPU. I get 30 FPS, easily, but don't have all the sliders set all the way to the right. I have DirectX 10 preview selected, anti-aliasing, and only bilinear filtering.
Summary: It Performs to my expectations... the 660ti sc didn't fix the issue I was seeking to fix... Framerate Game Lag. It turns out my internet connection in my household is being sucked away by ps3's on netflix and ipad/kindles on the internet
