New Laptop with 64bit CPU?

Hi all, it seems easy to add to this chat site. I found it doing a search for benchmarks for my Toshiba P15-S420. I also found a very bad site using the phrase "Toshiba S-420 benchmarks" which messed up my home page and brought up some very crass pornography so be careful what you open up. It is evidently an advertisement to get you to buy a antivirus program but however it does it was not caught by my copy of NORTON antivirus or my copy of PC-Cillin. Still it messed up my home page and I had to reset some stuff on my PC so I regard it as destructive.

Now for the question. I have had my S420 (3.03 GHz clock) for about three years and I have been pleased by it's speed but I am beginning to worry about the MTBF on my disk drive and perhaps other problems. I have had the power jack connector resoldered twice and now have taped the power cord to the case with a slack loop using strong duct tape so that if there is a tug on the power cord it will not break the connection to the mother board. I bought the S420 because it seemed to be the fastest PC at the time. I am a retired Scientist/programmer and I have coded and debugged large programs of over 100,000 lines of fortran or ALGOL over a 33 year career and I was delighted to find the WATCOM f77 compiler and have been using it for three years. My question has to do with the speed of the new 64 bit PCs. I see that some run at about 1.8 GHz which might be only slightly faster than a 3 GHz 32 bit PC. If I have to upgrade my PC to a 64 bit machine, what is the fastest 64 bit PC on the market today? Where can I find benchmarks for the 64 bit machines that compare to the S420 32 bit PC (without running into a virus laden site)?

Wait for Core 2 Duo laptop versions to pop up... the CPU is called

Merom.

Speaking of which, i wanted to know if it was worth getting the current core duo's over the new Core 2 Duo Merom, and also, i heard that the current meroms are only a 667mhz FSB... i tihnk... O_o

would it be worth it waiting for the 800mhz or higher FSB processors?

How's the performance difference in comparison of the Core Duo 2.16, the Core 2 Duo 2.16 and the FSB 800 or higher Core 2 Duo.

Def. wait until the Merom is released with an 800mhz FSB.

Not sure....But when they are released, you can just swap the two and the most you'll need is a BIOS upgrade.

I heard that you can't do it with the existing Core 2 Duo's because the FSB for the current laptops are at 667 mhz and the Core 2 Duo Merom runs on 800mhz FSB.

I'm not sure about this, but i think they were releasing a new board to go with the laptop as well O_o

But technically speaking, could you tke the core 2 duo 800hz and fit it into the 667 FSB motherboard and expect it to not blow itself up? =P

You are wrong... the first batch of Merom is 667MHz limited in order to be compatible with current motherboards. Read this nice Anandtech article.

And notice that upgrading from a Core Duo to a Core 2 Duo won't give you a significant boost unless you render 3D a lot on your laptop. Which means if you want to upgrade your laptop wait 2007 Q2... if you have to buy one laptop now go for the Merom.

Most games are GPU limited... Anandtech shows that only Oblivion gets some extra FPS from switching to a Merom.
