Need to buy a laptop $800 budget

Okay well i need to buy a new laptop ASAP since my old one overheated and died :| My budget is $800 sharp. It needs to be reliable that will get me atleast 2 years+ solid usuage. I play a decent amount of gaming (mostly runescape), youtube and just surfing the web. What i'm looking for is a laptop that will run runescape SMOOTHLY in HD, Good graphics and a decent cooling system (my last 2 laptops died from overheating). I did abit of looking around but i don't know what i'm really looking for in a laptop.. :| here a link to one i think is alright: http://www.ebay.com.au/itm/Sony-15-...7781937?pt=AU_comp_laptop&hash=item3a7f88e831

Suggestions Please?

 

Here is a suggestion to start:
HP i7 8GB Ram 720GB HDD
This is a decent laptop and is on sale for a good price. Can choose between backlit keyboard or standard.
Also, I'm, not a huge fan of buying laptops or major electronics off of ebay, bad experiences plus I just think it can be overpriced or you are being mislead and buying a crappier product. But that is my personal experience. It seems like the Sony Vaio batteries for your model don't have very long battery life from looking around.
Brands that are well known and will probably get you through the two years:
Lenovo (good quality builds in my experience)
HP (newer models, like the one above)
Asus (stick to newer models)
Check out this link Laptop Brand Ratings
Might be missing one but generally that is the list, Dell is also a good brand to look at, but it seems like they have been going downhill recently. But I did own a dell desktop for 5.5 years.
I will continue to look around for you, but i suggest you check out the websites of those brands though and then cross reference that on your preferred shopping site.

 

Do you need a laptop, maybe try build your own desktop then you won't have the overheating problem as much.

 

Well if i was to build a desktop, what parts would i be needing for an awesome gaming desktop in my price range?

 

Buy a desktop computer, that'll be more suited to gaming.

 

Also if you are looking at laptops, may I suggest buying a laptop cooler. They are USB powered fans that provide air circulation to the laptop

Also OP you will get more for your money and much longer lasting system if you build one.
