Hi,
As the title states I am wishing to upgrade my graphics card.
My System:-
Pentium 4 3gig
GA-81915PM Mother board
Intel 915P chipset
1 gig DDR ram
Radeon x600 256 card
PCI express x16
DVI-D connection
not sure if 300w or 450w power

My new card needs to be:-
512meg
ATI not nvidia
£50 or less (3 kids and wife budget)
As close to plug and play as possible as I am not a PC engineer
Not going to crash/blow up the rest of my sytem
suitable for BF2, BF 2142, C-Strike C/Zero and Source, U.R. Tournament 3
Better than what I have now.

Many thanks ,in advance.
