Hi People,
Below is my current desktop spec:
Intel Core 2 Quad Processor Q6600
2048MB DDR2
NVIDIA GEFORCE 8400GS 3D
The problem i am facing now is that whenever i play high end game
like bad company 2, it will get very laggy. I am thinking of
getting a upgrade on the graphic card, so the question
is:
1] Which graphic card should i get?
2] Do i need to upgrade my processor and ram to support my graphic
card?
3] How much will i have to spend?
Please help me. 




1) HD4850/HD5750. $180-$220.
2)No.
3) A new PSU is required to run the new graphics card. A nice
Vantec 500W can be had for $75.
So maximum you will need to fork out is $300.
