APPROXIMATE PURCHASE DATE: (2 weeks)

BUDGET RANGE: (US $1000-1300)

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: GAMING, anime, web surfing

PARTS NOT REQUIRED: Mouse

PREFERRED WEBSITE(S) FOR PARTS: N/A

PARTS PREFERENCES: Explained in additional comments.

OVERCLOCKING: Yes, but only as needed for gaming.

SLI OR CROSSFIRE: Extremely probable in the future (6 months or so)

MONITOR RESOLUTION: 22' 1680 x 1050

ADDITIONAL COMMENTS: I have two builds here, one intel and one amd... I know the generic response go intel/ddr3 if you have the money, but what I am more interested in is.... if I do go with the intel/ddr3 build about how much longer (1 month, 6 months, 1 yr?) will it be considered a "top end" computer as compared to the amd/ddr2, in respects to gaming. Basically I am just trying to optimize my buying power and get the most bang for my buck as well as making sure my purchase does not become obsolete too fast.
