Please suggest Graphic card for Asus P7H55-M LX

Well, most low end GPU will work for you(without any PSU change)
if you can spend a little more get HD 5670

else HD 5570 is enough

anyways which Power Supply Unit you have?

At his budget and config any PSU is good enough.

+1 .. U can look for 240gt as well. It don't required any extra power and u can use it as a physx card in future too.

@ OP - get this
Flipkart: Zotac NVIDIA GeForce GT240 1 GB GDDR5 Graphics Card: Graphics Card

HD 5570 is still better than the GT-240 DDR5 model too.
Check here: GeForce GT 240 GDDR5 vs Radeon HD 5570 – Performance Comparison Benchmarks @ Hardware Compare
So, get the HD 5570 1GB DDR3 for 3.3k from flipkart.

^^ lol .. that's just a lame benchmark site

for example take Avatar - HD5570 scored 22FPS and GT240 15FPS - when you click on the source link HD5570 got 15.90 and GT240 got 15.30 , IN BFBC23 GT240 18 FPS and HD5570 15FPS but actual values are 17.60 and 12.90 respectively

read these :

ATI Radeon HD 5570: Reasonable Gaming Performance For $80? : AMD's $80 DirectX 11 Card
PowerColor HD 5570 1024 MB Review - Page 15/33 | techPowerUp

in most of the benchmarks GT240 wins and the GDDr5 mem it has is clearly helping it to gain those extra fps.

^^ Thanks buddy.
