Eurocom's D900C Phantom-X is big, fast, and expensive.Three laptops with choice gaming and entertainment features debut on our desktop replacement chart. The sixth-place HP Compaq 8710p is sold as a business laptop, but has excellent graphics performance and a Blu-ray Disc drive. Toshiba's eighth-place Satellite X205-S9359 comes with an external USB HDTV tuner and an HD DVD player, and its subwoofer-enhanced sound is rich. The ninth-ranked Eurocom D900C Phantom-X, the first quad-core notebook we've tested, posted the fastest WorldBench 6 Beta 2 score we've seen from a laptop, but it suffers from pitiful battery life and a crushing price of $5158. In other news, a price fluctuation for HP's Pavilion HDX caused that machine to switch spots with Apple's MacBook Pro, which moves into first place.
