The amazon price is about the same as the
price on Scan - and yes, this is partly to do with Bulldozer coming soon, and also partly to do with how good Intel's new i5 2500 and i7 2700 are.
If you pair this with one of the new AM3+ 900-series motherboards you'll get a very capable system now (about the equivalent of an i7 920 in multithreaded tasks), and you'll be ready to upgrade to Bulldozer if it's worth it.
EDIT @CAT: From the OPs other threads they're planning a complete new build, not an upgrade, so they're starting from scratch. I'm not sure waiting for Bulldozer will really be an option for them!
