Graphics cards in laptops can not be upgraded. No good taking it to PC
World - they'll direct you to the manufacturer of the machine. As a guideline - laptop manufacturers will charge (on average) £200 to uplift the machine, take it the workshop, and THEN tell you how much it is going to cost.
There are two main graphics card types - NVIDIA or ATI. Some people swear by ATI - others NVIDIA. I myself am a NVIDIA person.
The graphics acrd attaches to the PC
in one of three different ways:-
1) PCI - the slowest
- until recently the fastest
3) PCI-Express - relatively new and the fastest
Check to see which connection your motherboard has.
With both types - the higher the number - the better it will be IE
NVIDIA FX5200 is not as good as an FX5600
ATI RADEON 9200 is not as good as RADEON 9800
As a rule of thumb, the more you pay, the better it will be.
As for laptops....buy a desktop or a new laptop
Be who you are, The world was made to measure for your smile. So Smile.
