difference between two MBP Refurb

Hi,

which is the more powerful?
Frankly, I'm lost there.Isn't the Core i7 newer? so why is it cheaper?

FC665LL/A (2149$)
Refurbished MacBook Pro 2.66GHz Intel Core i7
17-inch LED-backlit antiglare Hi-Res widescreen display (1920 x 1200 pixel)
4GB (2 x 2GB) of 1066MHz DDR3 SDRAM
500GB Serial ATA @ 5400 rpm
8x double-layer SuperDrive (DVD±R DL/DVD±RW/CD-RW)
NVIDIA GeForce GT 330M graphics processor with 512MB of GDDR3 memory

or:

G0GW4LL/A (2219$)
Refurbished MacBook Pro 3.06GHz Intel Core 2 Duo
17-inch high-resolution LED-backlit glossy widescreen display
4GB memory
500GB hard drive
8x SuperDrive (DVD±R DL/DVD±RW/CD-RW)
ExpressCard/34 slot
Built-in 8-hour battery
NVIDIA GeForce 9400M + 9600M GT with 512MB
Illuminated keyboard

Generally the FC665LL would be more powerful because of the core i7, not alot of difference between them though.

Probably because they just look at clock speeds.

Get the first but buy yourself a good 7200rpm hard drive.
