For under a grand, you're not gonna find anything with comparable specs plus a good graphics card. They have to make cuts somewhere in order to give you that price.
In addition to the weak graphics card, it's also worth pointing out that the machine you were looking at has a slow hard drive. 5400 RPM drives tend to chug. I wouldn't want less than a 7200. The faster you can read and write cache files, the faster and more stably SL (and all other applications that depend heavily on temporary files, like Photoshop, audio/video editors, etc.) will run.
I know the i7 quad and DDR3 are probably quite tempting, but if it were me, I'd probably rather go with a more modest CPU, and DDR2, if it means I can get good graphics and a better hard drive, for roughly the same amount.
A G51 is a pretty good example. It won't be quite as fast at non-graphical tasks, but its GTX 260 will run circles around that 310, and it's got a 7200 RPM drive. It's only $99 above your proposed budget.

No sense spending money on something that won't very well do what you want to do with it.
If you can go up to around $1600, a Lotus from Malibal is a fantastic machine. It's easily the best laptop on the market in its price range, in my opinion. It comes stock with a GTX 280M, which the absolute top of nVidia's mobile line right now. Trick it out with a 1920x1080 display (in a 15"!!!), the same CPU and memory you were looking at, and a 7200RPM 500GB hard drive, and the total price is just $1648.

The thousand dollar machine with the bottom of the barrel of graphics, would probably only last about 12-18 months before the graphic card just couldn't keep up anymore, and you'd only sort of enjoy the experience.
In my experience, good gaming laptops are always far less expensive in the long run than cheapo ones. It's roughly $400 a year for Lotus, vs. $1000 a year for the cheapo.
If that thousand dollars is burning a hole in your pocket right now, and you have to get SOMETHING, then I'd say get a desktop. For a grand, in a desktop, you could basically have everything you want: the i7, the DDR3, a MUCH better hard drive, and a nice graphics card.
Here's a quick example:

Those are my suggestions. Do whatever you think is best. Good luck.
