T5300 or T5470?

[Sticklyman]

Hi,

A friend of mine is buying a laptop. He has a choice between one with a T5300 or one with a T5470. The laptops are otherwise virtually identical. Which processor should he choose?

T5300: 1.73GHz Clock, 533MHz FSB
T5470: 1.6GHz, 800FSB

Sorry, I don't know the RAM clock for sure but I think it is 667MHz.

Fairly quick reply needed please - he wants to order tonight.

Thanks

EDIT: Just to add, I suggested the T5470. I will probably be labeled as stupid in a minute, then beaten up by my friend

Personally I'd pick the T5300. They're both Core 2's with 2mb L2 Cache and the only real difference is FSB. I don't really see the 800FSB of the T5470 improving performance (if at all) except maybe in terms of memory bandwith if memory on the T5470 laptop runs at a higher speed. At the end of the day, the T5300 uses the same core, a slower fsb but a higher clockspeed. The clockspeed outweighs the extra fsb speed in my opinion.

However, if you ever intend on upgrading the CPU in the laptop you buy, anytime in the future chances are the T5470 based laptop will have better upgradability as it uses the Santa Rosa 800FSB platform which I'd hazard a guess the T5300 based one might not. If I recall correctly, the Santa Rosa platform supports 800FSB socket 479 Core 2 Duo's up to 2.6GHz and may take Penryn based mobile chips with a BIOS update.

What are the brands and full specs of the two laptops out of interest?
