Which HP Business notebook, 8510p/w or 8710p/w

I have the opportunity to purchase one of these notebooks at a fantastic price and would like to know which would be better for playing games like Battlefield 2142.

The 8510p has the ATI x2600 256mb

The 8710w has the Nvidia Quadro FX1600M 512mb

I'll get either with the 2.0 or 2.2Ghz processor, 2gb memory (1dimm), blueray, and will upgrade hard drive to 7200rpm when Seagate releases the 160GB.

Which of these would perform better for games? I'm guessing about equal considering the x2600 is more consumer orientated and the Quadro is a more professional level card for CAD and such.

On another note, once I have one of these bad boys on order I'll be selling my current nc8430 w/ati x1600 256mb, Core2Duo T7200, 2GB memory, 100GB hard drive, DVDRW, 12 cell extended battery, w/over 2 years warranty left for roughly $1000obo

 

FX1600M would probably play games better even though it is a workstation card.

Keep in mind though the 8710 is a 17" laptop and the 8510 is a 15.4" laptop and the latter would be much easier to carry around.

Also HP to my knowledge hasn't mentioned anything about a 160gb 7200rpm hard drive coming (if you look at each of those laptops' product specification sheet).
