Don't know which your mainboard will support, but I would go for the first
one on the list.

You might need to do a BIOS update to support the newer chips.

The VT7 appears to be compatible with 90nm and 0.13u P4
processors and with Celeron D.

The third one in your list, is stepping G1, and looks
pretty new. Family code is 0F49. Power 89W

The first one consists of several steppings, and E0 is
the latest. Family code is 0F41. Power 89W

Unless the description of the third one, offers a feature
that I've missed, I'd probably take the cheap one for $107.98,
as it has everything the third one has got, and looks to
burn the same amount of power.

Since the OEM processors don't usually come with a heatsink
fan, you'll also be in the market for a neatsink/fan for
the thing. I'd spend a few extra bucks, and get a decent
one. My favorite is the Zalman 7000B, and there is one
here for $30 - I like it because you insert and tighten
two screws to install it. With your 89W processor, I'd
leave the fan running at full speed (plug direct to +12V
power on fan header). The only negative about the 7000B,
is wiring inside the computer, tends to get caught in the

(fitting info for 7000 series - your processor socket is not
right up to the top edge of the motherboard, so power supply
to motherboard clearance is not likely to be an issue) (AB)_478MBlist_eng.htm
