Now here's the dilemma - The laptop will be bought for a friend from a well known retailer as i can 10% off (and no i don't work there :p) so basically both models come to around the £400 mark which is his limit.

The laptop will be used as a live music tool. Specifically, the computer will load drum sample software that will be triggered via MIDI on an electronic drum kit and played out via our PA system via an external firewire soundcard.

The problem arrises with the nature of the software and latency issues. The software absolutely loves RAM and harddrive access times (and capacity for that matter). It doesnt mention what RPM the models are, but i'm guessing at this price it'll certaintly be 5400rpm. Realistically, how hard is it to change to a 7200rpm drive? All of the drum software takes up about 150GB, so looking at a 250GB at least for windows too and extra future expansion.

Finally, for the lowest possible latency, CPU speed is absolutely crucial. The two models have different CPU types. Whats the deal with the Centrino 2? Are they just Core2Duo's but revised for laptops for better cooling etc? How much better is the 2.0ghz 1066fsb model over the 1.83ghz? Basically, its raw power that is needed, not battery life or anything like that as it will always be plugged in.

If i go for the 1st model with 2.0ghz CPU, how much would it cost to upgrade to 4gb for the current 2GB installed, seeing as though its 1066fsb? 2GB will run the software pretty well, but 4GB would be a nice addition if we could upgrade for sort of £30 or so extra?

Sorry for the relatively vague wording of this, but i hope you can identify and answer my questions easily enough!

Many thanks. :)
 
The latency issues will relate primarily to the sound card and sound drivers. I would recommend he buy an external m-audio card and make use of the extremely low latency asio drivers. I can run 5-7 heavy VST instruments with cubase and rewired reason no problem on a p4 @ 3.6 with 3 gig of ram. It ran 'better' on a core 2 duo machine, but it really only effected load times. The real issue has always been audio driver latency, rather than seek/processing times.
 
Sorry i didnt mention before, but this will be paired up with a Presonus Firebox (firewire) device. Gives extremely low latency monitoring. :)

At the moment, a p4 @ 3.5 isn't good enough to run this software at a low buffer (latency) size, as we get get pops and crackles with a MOTU 828Mk2 Firewire device, thus we have to get a Core2 laptop to give us enough headroom :o

Unfortunatly we dont have 64-bit supported DAW software, otherwise i'd go with M-Audio + 64bit drivers and software.

I'm sort of leaning towards laptop 1?
 
#2 easy.

4gb ram, drum samples needs this.


in terms of performance, you will basically not miss the .2ghz in cpu. you'll get a 64 sample buffersize to run stutter free on either one.

id go for the one with faster cpu because its easy to upgrade ram but not to upgrade cpu

if one had more firewire ports than the other it might swing it too though
