Here’s a configuration from Mouse Computer (that assembles PC’s) that will allow you to compare what we get here in Japan to your local offering:

MDVADVANCE 9400GX, Pentium D 940 (3.20GHz), 2GB of DDR2 (PC2-4200), 320GB in SATA (160×2 RAID), DVD DL Multi, NVIDIA GeForce7800GTX DDR256MB with XP HOME for 1700 EUR, which is quite expensive in my opinion.
