X205-SLi2 and X205-SLi4 laptops; fast forward a couple months, and here we are yet again with two more updates in the X205 series. The latest duo of 17-inchers -- the X205-SLi5 and X205-SLi6 -- each pack the same pair of 512MB NVIDIA GeForce 8600M GT GPUs and a 1,440 x 900 resolution panel, but the latter ups the ante with a more powerful 2.4GHz Core 2 Duo T8300 processor. Furthermore, you'll find room for up to 4GB of RAM along with dual 160GB HDDs, Harman Kardon speakers, 802.11a/g/n WiFi, dual-layer DVD writer, Bluetooth 2.0+EDR and a 1.3-megapixel webcam. As for the X205-SLi6, you'll find a potent 2.5GHz T9300 under the hood along with 400GB of total HDD space, but basically everything else remains identical to that found on its lower-spec'd sibling. Check 'em out right now for $1,999 and $2,499, respectively.
