helo
i am new here and need yours help
i going to buy workstation laptop
and i wanted your help for understanding and choosing a laptop
the laptop is insted of my desktop computer (biger=better)
and i going to used it for Cad and 3d applications like :
solidworks 2010
maya
3dmax

whats is more important cpu or graphic card?

i am thinking on:

1. lenovo w700ds with Core 2 Duo processor T9600 (2.8GHz 1066MHz 6MBL2) and NVIDIA Quadro FX 2700M
or

2.lenovo w700 with Core 2 Extreme X9100 (3.06 GHz, 6MB L2, 1066 MHz FSB) and NVIDIA Quadro FX 3700M
or

3.dell Precision M6400 with Intel Core 2 Duo T9900 (3.06GHz, 6M L2 Cache, 1066MHZ and VIDIA Quadro FX 700M
or

4.asus G73JH A1 with intel i7-720qm 6mb cache 1.6GHz and 1GB ATI Radeon™ Mobility HD 5870

the asus got very strong cpu and very strong gaming gpu
and the w700 and dell got stronger graphic card (quetro) but weak cpu (Core 2)
what is the best choice ??
if somebody got better option for me i will be happy to hear it (about 2400$ max)

Any of the quadro's would be better for the programs you are running, but cannot play games at all. Basically if you want to play games and don't mind a slower card for your programs then get the asus, but if you will only use those programs then get a laptop with a quadro.

Id say #2 comes out on top.

1 2 and 3 basically have the same CPU (dual core at around 3 ghz) and also their cards are from the same lineup so the 3700M is better than the 2700 and 700.

As for #4 compared to #2... 4 is a quad but only at 1.6ghz while 2 is a dual at 3.06ghz, im mostly going to assume you will benefit more from the higher clock rate rather than having an additional 2 more cores. And the 5870Mobility Its hard to say how exatically it will perform in 3D rendering. In the chart ive posted above you can look up the 3DMark scores of your GPUs the 5870Mobility gets roughly 17% more score in the 06 version, but the 3700M has something the 5870M dose not, and thats optimized drivers with 3Dmax, maya, and solidworks. That will mostlikely make up the difference and more.


Id also like to ask you why you wanted a laptop exatically. You could build your own i7 920 with 12GB RAM and a desktop version of a workstation card for $1800, and it would be more than three times faster than any of the workstation laptops you have chosen above.

and if #2 (w700) is with 4GB ram and #4 (asus) is with 8GB ram
is it will change the "picture" ?

It’s kind of hard to say, yes more ram will help out, cad is ram hungry, but the more you use the more graphic intensive the task. If you did/can use more than 4 gb with the 5870M it would perform that much more slowly because of the complexity/size of the task it has to render. I’d still pick #2 for smoother performance.

Did you look at the Eurocom Panther? It is similar to the W700 in design, but contains all desktop components. The battery life isn't good, but everything else about it is amazing.
