In most cases, it isn't possible to upgrade a
laptop's graphics card. If you want better gaming
performance, the only sensible option is to buy a
The vast majority of laptops have integrated
graphics, which means the GPU (graphics
processing unit) is permanently attached to the
motherboard, and not removable as it is in a
desktop PC .
These days, a lot of CPUs contain the GPU, which
means that you would have to replace the
processor in order to upgrade the graphics. Taking
Intel as an example, you'll find that the same or
similar GPU is used as you work your way up the
Core i7 range. That means that even if you do
upgrade the processor, you won't get an
improvement in graphics performance.
Plus, such an upgrade will usually void your
Inn the case of the HP NX 9420 for example, the AMD Mobility Radeon X1600 is actually a replaceable part, but the only compatible alternative is another 256MB board: the nVidia Quadro FX 1500M.
Since Need For Speed lists 512MB of video memory as a minimum requirement, the swap won't help. And even if there was a better option, the fastest
available processor for this laptop (2.33GHz)
doesn't meet the game's 2.4GHz requirement.
How to add a graphics card to a laptop
There is a way to add a graphics card to a laptop,
but it's not for gaming purposes. Strange as it might

gives you an extra graphics output so you can drive
an external monitor as well as your laptop's built-in
screen. If your laptop already has a VGA,
DisplayPort or HDMI output, adding a USB graphics
card means you can drive a third screen: you're not
limited to two displays.
