I read it can only do starcraft 2 on low for a decent frame rate which isn't too big a deal, and the same for some of the higher end games that I don't even play or care about. Now if it can handle Skyrim when it comes out then everything will be fine. If not then there is no use being upset over something you can't fix...........Unless dedicated graphics cards in laptops can be replaced. I am not sure if when the call something a dedicated card whether that means it is not integrated, and if it is not I wonder if it is replaceable. Yes I know desktops are much better and cheaper for gaming, but I need a laptop for college and cannot afford to buy 2 separate computers.
I think there were some really high laptops that had the capability to change gpu's to an upgrade from the same laptop manufacture. But anything close to mainstream you're not going to find anything.
The biggest thing is how much video memory does it have and is the memory dedicated or part of the laptop main memory. Another aspect is the operating system 32-bit or 64-bit. A 32-bit operating system puts a real cramp on the total memory the unit can address. More than likely it's got a 64-bit OS and hopefully it has at least half a gig of video memory.
As a case in point, I'm running a nvidia 8800gt, which is about 5 years old now, and it has 512 MB of video memory. My system is running an older quad core intel cpu with 4 gigs of system memory. I'm also running Win 7 64-bit. I run Fallout 3 and Fallout: New Vegas just fine in fairly high video quality settings without a problem. Occasionally I'll get a little stuttering but I'm guessing that has more to do with Fallout than my system because it doesn't do it all the time, and it's fairly random, meaning it doesn't matter if I'm indoors or outdoors, action or walking. The only issue I think I'm having that may be related to my system is when I'm in an intense fighting scene and sometimes it will crash or the actions slows down significantly for a few seconds.
I tried to check Tom's Hardware for comparisons, but that's hard to do because laptops have odd series number gpu's. But if the GT 540 is anything close to current PC models, that a fairly fast gpu and as noted, you should be just fine.
