new intel processor - worth to upgrade?

Yes, I know that Quartus does not get much from multi-cores CPUs. So I know that there can be a problem with lower frequency of i7 CPU. But it is a new generation of CPUs, couldn't there be same difference as there was with P4 and Core2? Moreover as you say, the compile speeds depends on memory speed and I've read some test (but only with some syntetic benchmarks) that the i7 handles memory pretty well, there was about twice increase in memory throughput... Isn't here anyone who actually tested it in Quartus? I want to be sure before I make an upgrade of my machine, because another possibility to upgrade will be only in some far future.
