Did you try putting together an Inspiron 1520 instead? The 1520 has the option of a 8600m GT which is better than any option for the 1525. I'm not sure if there are any any downsides to the 1520 when compare to the 1525. Someone else may be able to fill you in on those. The 1520 comes with winXP which may be good or bad depending on your interests.
You can configure a much better spec laptop for the same price. I'd definitely suggest dropping the 3 gigs of RAM. Take 1 gig and buy a RAM kit from newegg or somewhere similar. You can get 4gigs for less than
Dell charges for the two gig upgrade.
for about 900 dollars you can get
Intel® Core™ 2 Duo T7500 (2.2GHz/800Mhz FSB/4MB cache)
Genuine Windows® XP Home
Glossy, widescreen 15.4 inch display (1280x800)
256MB NVIDIA® GeForce® 8600M GT
120GB SATA Hard Drive (7200RPM) Free Fall Sensor
6-cell Primary Battery and 9-cell additional Lithium Ion Battery
that is 939 with the 400 dollar rebate....You can also consider dropping the hard drive and upgrading that aftermarket too. I'm not sure what screen res. you prefer but that has room to change as well. But here you get the decent video card, near the best processor available for inspirons, a 7200 hard drive, and two batteries. Just an option.
