The entry-level Core 2 Duo E6300 seems to be the least inflated at the moment. ZipZoomFly is currently selling the chip for $193, just $10 higher than Intel's list price. Meanwhile, Monarch Computer has the Core 2 Duo E6400 in stock $17.99 above Intel's price at $241.99. Outlook above $300 is less rosy: the cheapest Core 2 Duo E6600 we could find was at Newegg for $369.99—nearly $54 above Intel's price—and markups just keep getting worse from there.
If Core 2 Duo prices are still too high for you, we've spotted some deals on Seagate's 750GB Barracuda 7200.10 hard drive. This drive launched around the $420 mark but has now dived to $349 at Mwave and $350.99 at ZipZoomFly. The 'cuda will still run you about 47 cents per gigabyte at that price, but it's hard to beat 750GB of storage on a single drive.
