Well maybe I can help since I can speak from experience.
I currently have the Dell Inspirion 9300 with the 6800 GO 256mb graphics, and intel 1.83ghz centrino, 1gig 433mhz fsb, 60gb hdd. This computer is a little over 1 year old and I can still play all of the top games. It performs just as well as my desktop with a AMD 64 3000, 6800 GT 256mb, 1gig pc4000.
Like I said I can play all of the modern games, BUT not real high resolutions with the eye candy turned on. I am talking mainly about BF2. CS:S is a piece of cake for it with 1024 res and everything set to as high as it will go though.
If i were you, i would do what the others have suggested and go with a dedicated graphics in your laptop. Personally I would get the 7900 GO series and 2gb of ram in the Dell XPS. I recommend 2GB of ram since my 1 GB in BF2 is barely cutting it and with laptops you want them to go the distance since you're limited on upgrades. Yes, this will cost you extra money, but its worth it. And besides, when you're talking about a gaming laptop, they're expensive in nature. Far more expensive than buyin a desktop computer with the same capabilities... (mine was $2300 when i first got it, but was still cheaper than the first gen of XPS and had better parts)
No way in hell will that integrated Intel video system push those games... I have a laptop with an ATI X1400 and it barely plays the Sims 2 at an acceptable pace... does fine for strategy games though. Bless you Paradox for Hearts of Iron 2.
can i play games like doom,battelfield,generals and other new games??
video/graphic chip Intel 915GM Express
That laptop WILL play the games, you listed, but in other games like Oblivion it will not.
The GMA900 is weak, it will play them, but damn slow! It uses software+cpu for all the vertex heavy lifting so it's very slow and you'll be stuck at low res. But if it's just for gaming while waiting to board a plane or such it'll do in a pinch, but it's not a gaming laptop by any stretch of the immagination.
With Oblivion it just won't play them at all, you need Oldblivion, and that's pretty much a view of games to come.
You'd be better off with either an X200 or GF6100 series integrated or better yet for starting to get a little bit more serious about gaming something discrete (minimum Mobility Radeon X1300 or GFGO7300 , IMO). For true gaming experience then an MRX1600 or GFGO7600 is a minimum entry with the MRX1900 or GFGO7900GS being their better parts and the MRX1900XT and GFGO7900GTX being the two top dogs (which you can also SLi if you're nuts, err. I mean like roasting nuts :twisted: ).
First it's a Desktop CPU so battery life is halved. Second you got slow memory with not ability to move it to the DDR2 of either the current top Centrinos, nor the next gen processors MErom & Turion AM2.
Second the hard drive is slow even for a laptop.
Also the X600 is now weak as a gaming laptop option for a new buy.
And for that price you could get a 17" laptop with beatter features.
Faster (but smaller) HD, slightly slower but much more efficient cpu, memory useable in the Merom and next gen Turion, and much MUCH better graphics chip (GF7600 will clobber not only the X600, but even the X700 in my rig heck add their performance together and you might equalt the GF7600).
Rule of thumb, avoid buying from BestBuy if you live in the USA, there are far better option out, there.
Umm... thats not really that good. As others have mentioned, the graphics chip is weak sauce. I have a GeForce6600go in my laptop and it really doesn't cut it for most games (BF2, Oblivion) even at lowest settings and its faster than an X600. I'd look into getting at least an X1600. You can pick up a well equiped Core Duo with an X1600 for about $1300. Its an Asus S96J on ibuypower.com. My friend has one and it runs Oblivion pretty well (all those shaders I guess). But if you want to future-proof the laptop I'd put down a bit more money and try to find an even better graphics card.
