HelpLooking for a CHEAP laptop

So I know this forum is full of PC experts.
I have some idea on computers but I still need a lot of help!

My PC is old. I thought it was good but it really isn't. I can't run old games such as CoD4 and TF2 smoothly on med settings and even on low, I get major lag spikes etc.

I'm looking for the cheapest possible laptop that can run most games like BF3 at preferably med settings, but low is fine. If a laptop can run BF3 on low, then it's likely to run most other games such as COD4 on high, TF2, WoW and many other games.

The games I play are very limited because I doubt my PC can run it on nice resolution with smooth gameplay so I don't bother buying games anymore.

Most of you will say I can't buy a laptop that will run most things nicely for less than $800 but is there anything out there much cheaper?

I've read that the Asus G73JH can run BF3 on low and that's not too expensive.

My price range is $400-$600 as I'm a teenager and don't have much money :/ My birthdays this month and my parents said they would upgrade a few things on my PC but I would much rather get a laptop. They won't pay for it all which is why the laptop must be cheap!

Please if you could link some cheap laptops and help me out, it would be greatly appreciated.

For $400-600 u cant get a laptop that can run BF3 on med or even low. But you can get a desktop that can run BF3 on low - medium for $600. The best laptop you can get only has Integrated Graphics which is horrible for gaming http://www.mwave.com.au/sku-31160331...DDR3_RAM_-_500

As you already pointed out yourself, Asus' line of gaming laptops is probably your best bet in terms of performance/price. However, have you considered ordinary PCs or must it be a laptop? I'm pretty damn sure that as long as you can salvage stuff from your old PC or have stuff like a screen, keyboard and mouse available you can get quite a decent gaming PC for that kind of money, perhaps even BF3-grade stuff (and by that I mean more than just med quality).
