Suggest a Graphics Card for my system

what kind of screen res do you play at and power supply do you have. if you don't have a very powerful supply, you want be able to use high end cards, and if you play at lower res, most of the best cards are just overkill

A GTX 260 216 core or GTX 275
Check techenclave.com or techshop.in or lynx-india.com for prices in India dude.They are all indian sites.I am also indian.

Its a Fronttech supply 450W (AC) / 240W (DC) out.

The screen is 19in LCD
current res is 1280*800
not sure what to set for the game

Get a more decent PSU first.

I second both the above posts. First a new PSU, then a new Vid card. Look for: Antec, BFG, Thermaltake, Zalman, PC P&C, Corsair, or OCZ. The pick up a 4830, or 4850 as either mid range card will do fine.

Guys i see that most of the newer cards require 650W PSU at least.
Changing the PSU is not a problem.

But the ATI RADEON 4850 specifies 450W. and the retailers suggest it as a equivalent to 9800GTX . (both with 1GB ram)

ALSO...

I ran Quake 4 on my system with a 8400GT with 512mb ddr2 which i got from a friend.
The res was set at 1024*768
While the disply seemed ok i felt the speed was slow.
ie. movement of the characters.

IS this part of the game or will be better after adding a better card. Will adding more system ram help with game speed.

I wouldn't go much on whats said on the boxes

and for your budget theres not much you can't have but the top of the line gear

but I'd go for a xfx HD Radeon 4890 Black Edition 1 gb

8400 GT is too low power card dude. Go for a 9500GT atleast for that resolution.Or a HD 4650 or 9600GSO
