hey please give me your imput on the specs i've picked so far. i'm looking into getting an alienware laptop for college and for playing games. the things i'm mainly stuck on are mainly the graphics card, ati 5850 vs nvidia gtx 260. i'm little worried about the 5850 because i read if your laptop vender uses ddr3 memory for the card it will run slow, which confuses me. also i'm a little unsure on which processor. but i've done a lot of research and here's what i've picked so far:
processor: i7 620
os: windows 7 home premium 64 bit
video card (this is what i'm stuck on the most): 1 of these 3 which are all 1gig (ati 5730, ati 5850, or nvidia gtx 260m) the ati's have directx 11 support which will be good for future games, but i'm still confused about this "The memory interface of the Mobility 5850 is composed out of two 64 bit wide controllers leading to a 128 bit memory bus that can access up to 1024 MB of DDR3 or GDDR5 memory (512 MB GDDR3). If (G)DDR3 is used by the laptop vendor the performance clearly suffers noticable." - that's from

ram: 4g's dual channel ddr3 at 1066mhz
hard drive: 500 gig SATAll 7,200 rpm
