Someone help me on making choice of the laptop to buy..... i need a fast and good one,, please ideAS on what to consider. is it the processor? the RAM? or what? pls guys shed me light on what to do...........

For a general user its the processor. For a gamer its the graphics card of the system.

Get a minimum of an Intel Core I3 processor. Don't go for an AMD processor as Intel processors are better on the average.

The higher end processors are the Intel Core I5 & core I7 processors. They also come in generations ranging from 1st gen to 4th gen.

The RAM is not so important as it is easily upgradeable. Go for a minimum of a 6 Gb RAM. 4 Gb Ram is also o.k

The hard disk size should be a minimum of 500 Gb.

For Graphics Card, it should be at least a 1Gb Nvidia or ATI graphics card. Nvidia graphics card are better on the average

Then there are other peripherals like SSD drive, bluetooth, backlit keyboard, 3.0 Mp Webcam, HDMI port, USB 3.0 ports, Thunderbolt & Firewire ports e.t.c

thanks @wman .. so model or anything like that doesn't matter right

Model doesn't really matter. HP laptops are generally cool since spare parts are easy to find. Dell laptops are stronger on the average and Acer Laptops generally have longer lasting batteries.
An HP DV6 laptop could be entirely different from another HP DV6 laptop so get the exact specs right before buying.

oga, can u please recommend any other good HP laptops apart from DV6?

There are many good HP Models e.g DM4, DV6, DV7, G6, Envy M6 etc. There are also different varieties of laptops under each model type. So don't keep a particular model in mind go for the exact specs first.

the specs am seeing here .... there is no nvida or ati graphic card yet .... like it'snot popular ? or can u link me up ve abt 80k ..

N80k won't get you a new laptop with an ATI or nvidia graphics card. You could go for a good refurbished laptop with the graphics card with N80k at Computer Village in Ikeja. But If you're not much of a gamer then buy a good new Dell laptop, they are generally cheaper than HP.

@Wman, wat anti-virus do u recommend I get for my system?

I think AVG is the best. The 2014 version is out. Avast is also o.k
Make sure you update at least once every 2 weeks.
