$700 gaming laptop computers are uncommon in the current gamer laptop market. Gaming laptops are typically priced starting around $850 and increasing to over $6000. Please note that online computer stores associate the term "gaming" with select laptops as a way to indicate that a given computer is capable of handling gaming at a high level. There are probably laptops available on the computer market that are gaming-capable but aren't called out as "gaming" laptops. For simplicity purposes I tend to go by what the online computer stores label as gaming-capable laptops and with that strategy I can say with confidence that $700 gaming laptops are not always available to buy.
I suggest the following set of minimum technical specs for any $700 gaming laptop computers that might be available: 2.0 GHz Intel or AMD dual-core processor, 2 GB system memory, 160 GB hard drive space, and 256 MB dedicated video card. If you're a serious laptop computer gamer then I would boost the processor speed to at least 2.4
