So that's a total ticket price of about $250-$310 USD. I've been using AMD machines in my home for five or six years, now; generally, when one box gets upgraded, parts of it (especially the CPU) get put into a different box to upgrade that. That hasn't been possible on Intel. An Intel-supporting motherboard with the level of contemporary features I want becomes my first hurdle. Just for the base set of features I'd want (6 current-speed SATA ports, max "supported" RAM of 32GB, LGA1155), I'm looking at $230 and up. For a processor? $200-$320. And I'd want an i7, not an i5, so we're talking upper range. Yes, the early Bulldozers don't measure up to the Phenom II, but amdfam10 is going away, and Bulldozer will get past that mark. Rather similar how Intel's early NetBurst cores didn't manage to beat Pentium IIIs, but later ones did. (Yeah, NetBurst eventually bit the dust, and for good reason. I have to think, though, that a lot of what Intel learned with NetBurst went into preparing them for Sandy Bridge's incredible overclocking range.) So, yeah, while I'd love a performance-grade Intel desktop box, it's going to be hard to justify the price ticket. Even if I don't manage to get an IvyBridge desktop box, I do want to get my hands on an IvyBridge i3 motherboard; that RDRAND instruction is going to be sweet in a network gateway machine, and the power consumption deliciously low. -- :wq

There are some packages which seem to break: - - firefox and thunderbird, if I remember correctly - - chromium (theres an open bug on bgo) - - hardened-sources: the neccessary gcc-plugins don't work because they can't find the right symbols because gcc-4.7 is normally compiled with g++ which mangles the symbols. Don't know how to work around that, though it seems to be possible to compile gcc-4.7 with gcc - I just don't know how For all packages which break it's possible to switch to your old gcc-version (unless you uninstall it).

I tried an emerge -ev world yesterday (on a box with a total about 1100 emergeed packages), so far only had compiling trouble with gst-pluings-ffmpeg (gcc4.7.0 bug including patch is on b.g.o[1], so was easy to solve) and firefox 12. All of KDE 4.8.3 and libreoffice did emerge nicely. Though i did not test the results yet. SaCu [1] https://bugs.gentoo.org/show_bug.cgi?id=407741

As GCC-4.7.0 appeared for ~amd64 now ... anyone recompiled system or world with it already? More advantages or disadvantages? Thanks, Stefan
