Here's the graph you've seen before, detailing the DivX-encoding results. Nothing new here.

You may well want to do more than run a single application at one time if there are four cores and eight threads on tap.
We've now we've added a 1080p QuickTime clip into the fray, being rendered at the same time. What we're seeing here is how much the DivX encoding time is being compromised by the additional computational load presented by running the high-resolution clip on a looping basis.
Even with the additional load, the 975 EE is just about as fast as a 965 EE when running DivX concurrently.

Here's the same test but with the high-resolution Enemy Territory: Quake Wars running, looped, in the background. The observation, above, is reinforced in this benchmark.

| 81.77 | 81.61 | 80.3 | 81.73 | 79.55 | 83.13 | 76.03 |
And the ET:QW benchmark results with the DivX in the background. All quad-core chips do exceedingly well here, and it would be difficult to visually pick a winner, no matter which CPU - a £150 Phenom II X4 940 BE or Core i7 975 EE - was in the socket.
