Alienware m17 3870x2 ....CPU?

I was wondering what kind of difference would it make if i got the p8600 instead of the high end quad core cpu's. (Consider MFSX and Crysis)

I don't have the money to get a quad core processor this is my m17 setup what kind of fps will i get in games?

- Dual 512MB ATI Mobility Radeon™ HD 3870
- Intel® Core™2 P8600 2.4GHz (3MB Cache, 1066MHz FSB)
- Genuine Windows Vista® Home Premium (64-bit Edition) with Service Pack 1
- 2GB Dual Channel DDR3 SO-DIMM at 1066MHz – 2 x 1024MB
- 160GB 7,200RPM (8MB Cache) w/ Free Fall Protection

PS I will upgrade RAM to 4G and I will get more Hard Drive Space.

With all that said will this notebook suffer from the CPU?(in regards to FPS in Hardcore games)
- if so how much
How much of a difference in fps will i receive if i upgraded the CPU?

Instead of AW M17 why dont u go for ASUS W90 ? it destorys the AW model and has a lower price.

But if u want to go with M17,a 2.4 dualcore CPU can handle games fine but not all,for example World in conflict/FSX depends much from a better CPU,as logan said it depedns on the game that u play.
