OK, I already granted you that the FX line is overpriced. That's given.
The E6300 is barely slower than the FX 62, but it's also barely faster (sometimes) than the equally-priced 64 X2 4200+ (see the next chart after the one you pointed out)
This supports my contention that at or below the E6300 / X2 4200+ price ($182), the Athlon is still a perfectly good choice for a home computer.
...and the Core2 motherboards still cost more.
GIGABYTE GA-945P-S3 Socket T (LGA 775) Intel 945P ATX Intel Motherboard - Retail $90.99
I don't think thats very expensive for a motherboard...
PCI Express x16
PCI Express x1 (3)
PCI Slots (3)
Number of DDR2 Slots 4 x 240pin
8 Channel Audio
Gigabit Lan
4 X SATA 3Gb/s
8 X USB 2.0
Not the greatest but if he's NOT going to overclock... its not terribly expensive, and should he choose to it will still allow for some overclocking...
