Hello again.
I just did a performance measurement and percentage of performance in a game like Skyrim, to see how much CPU and GPU is utilized. In other words, to verify how much bottleneck that processor produces to the GTX 460. According to the GPU-meter, it was indicating that the GPU, which is the graphics card, in the areas of more load, such as in the open fields full of trees and fog or rain, reached a performance above 80%, and in some cases reached 90%.
Keep in mind that this game, with the Core 2 Duo and that card, plays Skyrim at 1440 x 900 resolution, high details, and uses 8 AA and 8 AF.
With the GTS 450, games like Skyrim, at that resolution and at that level of detail, although playable (it does not go below 30 frames per second at any time), but said graphics card goes to the limit.
Now, when passing the 3DMark11, the GTX 460 on the Core 2 Duo was performing at 100% in the four game tests.
