Nij, if you have not purchased yet, I've been doing the 'gaming laptop' dance this week myself. that's not a bad unit you've found for an instore item, but I would like to throw out to you a unit I came across this week in my search.
For the money you are looking to spend at BB, you can custom build an HP DV7t with a 17" display, 1440x900 (icons/text on a 1280x800 screen are just too big on screens over 14" to me), 9600M GT 512
w/ dual layer dvd burner, wireless N and bluetooth, 320gb hd, 4gb ram, P7350 or P8400. So a somewhat better "gaming" laptop as it uses the GT instead of the GS if you customize it that way. You may need to wait on a good coupon though if you want to order from HP.
Tuesday HP had a 30% off coupon which would have made this unit under $1,000 (so if you wanted to spend $1300 you could have gotten a 3yr full damage protection plan to boot or upgraded the CPU, HD, or display). That coupon didn't last a day before it was used up, so gotta wait for that one again.
or, you can find these in remanufactured form on ebay, I found essentially what i just listed above for $950 with at least 1.5 yrs of a 2yr warranty still intact.
I've been focused on finding a laptop with BlueRay so I can use it as my BR player at home, and watch BR at a night job I have. I initially found a refurbed HP 9830 built just like the dv7t except with a T5550 cpu and 8600GS and HDTV tuner included, for $789. The 8600GS is at least twice as powerful as the old M9800 in my old Dell 9100, but for less than $200 more, I decided the 9600GT would simply be more useful longer. (and I can always add the HD tuner later as that interests me as well).
either way you go, enjoy !
