    Take the i7. Better CPU for the same price and a better card.

    Although if you care for GPU memory size, better GDDR5 speeds, 40nm fab, and DX11 when gaming in Windows, get the i5. The i5 is the same as the i7, except the i5 lacks Hyperthreading. Tests show, the i5 is better suited for today and the future when it comes to mild multi-threading and single threading tasks.

    Better card ?

    The GPU in the 2009 i7 isn't better than the 2010 i5 card ?

    They benchmark pretty close, although the 4850 512MB actually benchmarks slightly faster albeit by a small margin. The 5750 has some better features though to make up for the slightly slower performance like 1GB RAM, lower power consumption, dx11 etc...

    The only reason for the mobility 5850 to benchmark lower than the mobility 4850 would be that it had GDDR3 or DDR3 vram instead of GDDR5. GDDR5 provides twice the throughput as GDDR3, you could call it pseudo quad data rate ram-- which doubles the gpu's memory bandwidth, making up for its 128 bit bus instead of the 256bit bus the mobility 4850 has.

    get the i7. you're going to want more cores at some point!
