Which is better?

I'm getting a gaming laptop, I'm not sure how important the CPU is vs GPU when it comes to gaming.
so I need some opinions on which setup would be better for extreme gaming.

1.
Intel® P8700 45nm "Montevina" Core™2 Duo 2.53GHz w/3MB L2 On-die cache - 1066MHz FSB 25 watt
SLi ENABLED DUAL (2) 1024MB PCI-Express nVIDIA GTX 280M's (2048MB Total) w/GDDR3 DX10 Video Cards

2.
Intel® T9900 45nm "Montevina" Core™2 Duo 3.06GHz w/6MB L2 On-die cache - 1066MHz FSB 35 watt'
nVidia GeForce GTX 280M 1,024MB PCI-Express DDR3 DX10


Edit:
is there a noticeable difference between the following 2 laptop CPUs? the second one is like $400 more expensive.
1. Intel® T9900 45nm "Montevina" Core™2 Duo 3.06GHz w/6MB L2 On-die cache - 1066MHz FSB 35 watt

2. Intel® X9100 45nm "Montevina" Core™2 Duo Extreme 3.06GHz w/6MB L2 On-die cache - 1066MHz FSB


thanks

  2. The X9100 is an "Extreme Edition" processor, that is why there is a massive increase in price. All it means is that the multiplier is unlocked, and I don't see any importance in that with a laptop.
  3. +1. That laptop would probably already produce a large amount of heat while gaming, and overclocking it will add even more heat.
  4. i didnt even no they made xtreme editions for laptops, there entire market must be antartica, liquid cooled laptop anyone?
  5. wow, seems like CPU isn't that important for gaming.
