Engadget says ”Here to heed your call for blistering frame rates is MSI, which has gone and refreshed two laptops from its gaming lineup: the 15.6-inch GT683DXR and its big brother, the 17.3-inch GT730DXR. While both retain the Core i7-2630QM from their forebears, the duo now feature NVIDIA’s beefy GTX 570M with 1.5GB GDDR5. And just like their predecessors, either can be stuffed with up to 16GB of RAM, dual 500GB or 750GB drives and a Blu-ray burner. Also on board is a premium sound system from Dynaudio, four USB ports (two of the 3.0 variety), Gigabit Ethernet, VGA and HDMI sockets and, of course, 802.11b/g/n WiFi.They’re on sale now, starting at $1,699 for the 15-incher and $1,799 for the 17-inch variant. MSI was kind enough to send us the smaller and lighter of the two, so hop on past the break for our brief impressions”.
