Left 4 Dead 2
In Left 4 Dead 2, we got our data by recording and playing back a custom timedemo comprised of several minutes of gameplay.

Here's another example of the 5830 barely outperforming the Radeon HD 4870, which isn't really a good omen for a $240 graphics card. Once again, the GTX 260 is faster at the highest resolution, too.

On the historical front, the GeForce 8800 GT continues to spank the Radeon HD 3870 in newer games. The 3870 can't really handle this game at these quality levels. And yeah, the GeForce 7-series cards are overmatched yet again. Purely in terms of frame rates, at 1920x1080, the 5830 is seven times the speed of the GeForce 7900 GS. Yeah, it might be time to upgrade.
