Just poped into town and bought a new graphics card for my pc
a geforce fx5500 256mb
Running P4 2.8
768mb ram

Now he suggested that i might need to upgrade my motherboard etc as i still have some problems with running games

like for example Command and conquer and i choose a 8 player map
it just gets slower and slower
as the game goes on

However my laptop plays the game so fast its just unreal and thats got a 64mb card with a p4 1.6 processor 2mb cache memory


I need to know how do i check what motherboard i have etc the comp is over 2 years old now
also any other upgrades i should do
