We're still happy that it's a quad-core CPU, but with a lower basic frequency: 2.66 GHz is the default. On the hand, hyper-threading is gone, but the powerful Turbo mode is still there. Depending on how hard the processor has to work, it can adjust the frequency from 2.66 GHz up to a maximum of 3.20 GHz. It's a great way to make sure performance levels are up there with apps that put all four cores through their paces.
Like the 800 series, this really is an eco-friendly processor. While it's idle, its consumption was very low at 84 W for the whole computer: Intel has obviously included an incredibly powerful energy saving system. When the processor begins to work, the results are reasonable for a quad-core processor at 191 W.
In general, the Intel Core i5 750 beats AMD's Phenom II X4 965. In every test, we found that Turbo mode allowed it to do keep up the pace for apps that didn't make much use of its multiple cores.
One example of this is iTunes 9.0.2, which we used to encode an album as MP3: it took 1 minute 25 seconds on the i5 750 and 1 m 31 on the AMD X4 965. In Adobe Ligthroom, though, the discrepancy is more noticeable: exporting our RAW photos took 4 m 57 s on this processor, compared to 5 m 47 on the Phenom II.

Games don't worry the i5 570 and it's an excellent choice. As a general rule, it should have no problems powering a high-end graphics card. When we tested it, we found results similar to the Core i7 870, with, for example, an average framerate of 64 fps in Far Cry 2.
