Hi there, JLV2k5.
What laptop is best for you depends on what you are after. Generally speaking, i would go for a HP Pavillion or a Dell, however thats just my opinion. If you are after the best gaming performance, the Dell XPS range is for you. The XPS M1730 is the leading gaming laptop in the world, and if you're serious about your gaming, the XPS can be fitted with QuadCore processors (2.53GHz) or a DuoCore processor (3GHz). It is really a desktop replacement, as it can reach excrutiatingly hot temperatures and isn't something you want to be stuck with on the go. The amazing capabilities of an XPS will come at a price however, starting at $3000 for your basic XPS M1730. The XPS M1530 and the M1330 are a little more comforting financially and offer the portability and performance Dell is known for. If you are after a more business-orientated experience, may i suggest a smaller more portable notebook. Asus is you're specified brand in this genre; they are renound for their amazing battery life and portability. Moreover, if you are after a laptop which will give you all-round excellence, i would strongly suggest having a closer look at the HP range. You just can't seem to go wrong with an HP - one of the most reliable notebooks out.
I hope I have been of assistance!
