please show us modern benchmarks that prove this i.e 1680x1050 supreme commander for instance, otherwise its just meaningless
I apologize that places like Tom's don't have benchmarks for something as obvious as "more powerful processor benches higher in CPU intensive application"; raising resolution in an RTS like Supreme Commander does not offload the work that makes it a stressful app on your CPU in the first place. But seriously, what does that matter, exactly? I don't know if you noticed, but - contrary to what this board at large may claim sometimes - new PC games and applications are in development. Regardless of how much more work we're able to offload to any GPU, CPU utilization is still extremely high, especially as more and more games are designed around multiple cores.
If you had few particular apps or games in mind, and your only goal for that entire PC was to hit your goal, I am absolutely sure you would be just as happy with a 3MB L2 as you would with a 6MB L2 if that particular software was not going to be largely affected by the slower CPU performance.
However, it doesn't change the fact that processor cache has a direct impact on CPU performance no matter
what the processor is doing, because it's always faster to access cache than it is main memory. If you are not as concerned with upgrading the CPU sooner than later, then take the savings now and buy again earlier, by all means. But it really has no bearing on the fact that cache size is directly related to CPU performance, and any game or app that finds itself waiting on the CPU's next cycle will gain from that.
As it stands, pretty much every modern MMO (FFXI, WoW, EQ2, hell even LotRO) as well as RTS (Sup. Commander, Universe at War, Dawn of War) is going to see gains because of how much they ask of the CPU. This is only going up - games like Dawn of War 2, Endwar, StarCraft 2, WAR - because these types of games have no good way to move that work off the CPU at any resolution. Even now, other games are only just starting to become more GPU dependent to where the GPU is becoming the key factor to increasing performance. In some respects it's definitely getting better, as we've just recently seen nVidia finally get their PhysX drivers out the door which will allow those particular types of comps to be calculated on the GPU, but it's not there yet, and realistically it won't be for some time to come.
