Not really. While consumers at home had 8MB, Intel was already looking to compete with PowerPC, DEC Alpha, MIPS systems where 4GB wasn't really out of the ordinary, so they knew where things were going.
Interestingly, while the Intel 450GX chipset was designed to daisy-chain DRAM controllers (1 controller chip per 4GB of RAM), none of the boards that actually could take >4GB used that, instead building their own solutions. Presumably that meant that there was a bug in the chipset.
Anyway, each of those 5 computers would have run you at least $500k in 1998.
(I've been on-and-off trying to acquire one of those boxes for a few years now.)
200 9.1GB SCSI disks for 1.8TB!
And still only 4GB RAM on that SQL Server 6.5 box they used for TPC-C. Wild.
And yeah, $770k for that server.
Edit: I guess whilst I'm at it...
