tl;dr all the reply's
I too concur with the ASUS Laptops being the best for the money right now.
Just remember that 95% of ALL the Laptop Intel CPU's are either only Dual Core or Dual Core with Hyper-Threading to make it look like it has 4 cores. The are just two extra logical cores virtualized by the two physical cores.
Now this isn't that bad for a laptop since the physical 4 core CPUS do wear the battery down quicker. But they won't perform as well as a true Quad Core would.
I'm not up on the AMD offerings right now so I can't comment on those.
But if you would prefer a laptop with the True Intel 4 Core
cpu you will be a $1,000 & above. Outta your budget for this I know.
This from here saves me having to re-type the info:
[Solved] I5-2410M Cores vs Threads - CPUs - CPU-Components
"If you want a laptop or an all-in-one PC with a quad core Intel CPU, then you need to get something with a Core i7 CPU. However, not all mobile (laptop) Intel Core i7 CPUs are quad core; some are only dual core CPUs. On the other hand all desktop Intel Core i7 CPUs are quad core.
There are many mobile Core i7 CPUs so I'm not going to list them all. Here is how you can tell the difference though:
1. Core i7 ending with "M" are all dual cores; example: Core i7-2637M.
2. Core i7 ending with "LE" are dual cores embedded into the motherboard; example: Core i7-2655LE.
3. Core i7 ending with "QM" are all quad cores; example: Core i7-2630QM.
4. Core i7 ending with "QE" are dual cores embedded into the motherboard; example: Core i7-2715QE.

I personally don't like how they taut the damn i5's as a Quad core when NONE of them are. They're using Hyper-Threading for two extra "Logical Cores".
You have to be careful with the i5's though because not all of them have the Hyper-Threading that you WILL want.
I helped my Postman pick this ASUS out a few months ago and it's pretty nice for the price.
ASUS - Notebooks- ASUS K55A
Newegg has them refurbished for $444.99 right now. Regular $699.00 new.
Newegg.com - Refurbished: ASUS K55A-RBR6 Notebook Intel Core i5 2450M(2.50GHz) 15.6" 6GB Memory 750GB HDD DVD Super Multi Intel HD Graphics 3000
I also like Lenovo's and the IBM Think pads.
Good Luck in your hunt!!
DISCLAIMER: I don't give a DAMN about the weight of a Laptop. ASUS says it weighs about 2 lbs with the battery in it. Is that heavy? NOt to me. I all I care about is that it WORKS, it's pretty durable, and I'm able to SEE the screen!!! Lulz
