yea make your own if you don't want to i recommend the toshiba satellite pro or just satellite series
Never use Intel it sucks use AMD it's cheaper, better, and all around more efficient same as for HD Radeon
My Computer Specifications:
AMD Athlon x4 @ 3.9 GHz (overclocked)
16 GB's of ddr3 ram
HD Radeon 5750
;D build your own cheaper + fun
Just build you're own gaming rig bud. Go to TigerDirect or Newegg and hunt out some parts. It will be way cheaper and in some cases it will crank out even more power since some Computer Companies clock down their hardware. I know from experience, and you will have some fun in the process
I somewhat customize my computers, and I sell them to neighbors and the neighborhood cholos. To tell the truth, if you want to get the cheapest option to get a great gaming computer, I would say build your own. Here's the link to the site that gives you the basic idea of how to build it. Granted, it won't guarantee success, but if you follow the directions, you'll have a 95% chance of getting a computer even better than Alienware: How to Build a Computer 2011
Now, I would recommend you read that, and then buy the equipment, because it really matters EXACTLY what outcome you want. Buy the equipment (Mother board, CPU, Fan, RAM, DVD/CD, sound card, processor, Sound card, MOST IMPORTANTLY VIDEO CARD, etc.) and then, follow the instructions here. If done right, it will not only run Combat Arms flawlessly, it will NEVER LAG...Unless you're internet sucks, in which that case, you're screwed no matter what.
Now, if you don't really care for working and saving and just want to get it via mail or UPS, go with Alienware. Right now, I think they're still having a sale on their m11x laptop, somewhere around about $600 if you order it normal, a bit more if you wish to customize. Otherwise, go to the nearest Best Buy or nearest nerd and ask them what's the best gaming computer they have for under $1,000. It'll work. Here's the link to the Alienware I was talking about: Alienware M11x Laptop Details | Dell
Have fun with your new awesome gaming computer of uber pwnage.
