Which laptop is right for me?

Hi everybody! I want to buy a laptop within semptember. This is that i need: 1GB ram strong cpu wireless and bluetooh integrated graphic card not important large hd (120,160GB) Anyone know any laptop with these features? And, at first, how much it cost??? Thank you enrico VentoEngine corp. Program your life ^^

Most laptops will support everything you mentioned except blue-tooth, that limits the list somewhat.... However, what do you consider a "strong CPU?" Do you want Dual Core? (AMD dual core laptops are available from one or two sources, though not sure of bluetooth integration -- the dual core Centrino architecture was just announced recently and new laptops are expected soon, google for "Centrino Duo") or do you want a strong single core? do you prefer a strong instruction cache with an intelligent pre-fetch (centrino) or just a brute force faster CPU? (efficient use of speed or just speed) Certainly if the graphics is not important, the Centrino makes a very good laptop (and even some of the Centrinos drop the Intel graphics and add 3rd party graphics). And the top of the line Pentium M processor is still decent at 2.13ghz, the intelligent pre-fetch makes it seem much faster. The new Duo has some interesting characteristics that make it intriguing beyond any other dual-core chip, I don't know yet if that is good or bad. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

I was watching for the new sony vaio dual core. I need a good cpu to use visual studio as fast as possible... I dont wanna become old waiting the compilation ;P VentoEngine corp. Program your life ^^

Actually get one of the 100gig 7200rpm drives. Compilation is multiple issues, disk to memory, memory to CPU and CPU crunch, and back to disk. I don't have a copy of 2005, but I don't believe any of the previous versions supported a multi-core compile, so the physical CPU will only be one-core for compilation. As others have mentioned, you will still see a small improvement because the other threads for OS activities and overhead might be taking 2 to 5% of the CPU and those move to the 2nd core to let the compile take the whole thing. If you go dual core, don't downgrade your CPU speed rating thinking two cores will make up for it. This is my favorite thing to do if someone is looking to improve or not loose speed on compile. run perfmon in windows make sure the following counters are active: Pages/sec (memory) % Processor Time (Processor) Disk Bytes/sec (Logical drive -- on the drive you are compiling under. Make sure the colors are set so you can see the difference, leave it running in a corner of your screen and do a build-all. You will then see the lines go mad. When the processor line spikes high you are using your CPU hard, if it peeks at 100% you are bound by the speed at that point. If memory spikes, you know you are using your memory hard, that height is adaptive, so you can never tell if you are memory bound, but you can infer that you are if the memory spikes at the same time the processor drops. And when the disk readings spike you know you are using your hard-drives hard. The combination of those three activities is what makes for your choice in machine. If the drive rarely spikes, then you can down grade the disk speed with minimal affect, if memory rarely spikes, then you can down grade the memory with minimal affect. But that test will show you just how much of your Memory/CPU/Disk combo you are abusing. I abuse them every day. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

After a year of hardcore development in Visual Studio 2003 (C++), I can recommend something like: AMD64 (I'm runnning a 3400+), as much RAM as you can afford/fit in(1GB for me), 7200 rpm hard-drive... I've found that to be around 20-30% faster for builds than a roughly equivalent 3GHz Pentium 4 setup (1GB RAM, 7200 rpm drive) we also have. Also, a high reolution screen is nice (I've got 1400x1050)
