Graphics Card Upgrade

[Twentymac]

My brother wants a graphics card upgrade on his laptop but i wasnt so sure about if this was possible.

His laptop is the Sony Viao PCG-GRT816S

Specs

# Intel Pentium 4 2.8 Gigahertz
# Microsoft Windows XP Home Edition
# 80 Gigabytes of Hard Disk Storage
# 512 Megabytes Fast DDR RAM (Low cost double memory Offer - call for details)
# NVIDIA 64MB Geforce FX G5600 Graphics

A Fairly old , yet reasonable spec.

I've found a few graphics cards that have come out of other sony laptops on ebay.

Just wondering can it be done ?
