I'm going to buy any one between these two cards - :

1.SAPPHIRE GRAPHICS CARD HD 7750 1GB DDR5.

2. Sapphire AMD/ATI Radeon HD 6670 1GB DDR5 Graphics Card.

My first question,which card will be better,in terms of value for money & performance.
And both the card require atleast 400 watts of power,now i use a 450 watt zebronics PSU,but don't know whether it will be able to support these cards.SO should i go for a new PSU or stick to my old one.If yes,then which one will be better A Corsair 450 or an cooler master 450 ??

What display resolution will you be using?

At display resolutions below 1920x1080 the performance per currency unit is the same. At display resolutions from 1920x1080 and higher the performance per currency unit advantage goes to the Radeon HD 6670.

In terms of performance only the Radeon HD 7750 has at least 30% more performance than the Radeon HD 6670.

Preferably your power supply should have a maximum combined +12 Volt continuous current rating of 20 Amps or greater. Look at the label on your power supply for its +12V rail. If it doesn't have 20A or higher value then it's most likely insufficient.

Can you specify your budget best bet will be 7750 because it can play far cry 3 , COD black ops 2 ,bioshock ,bf3 and many more games in medium high setting at a very good fps this is user review it is smooth as butter in these games your PSU Is good it will handle your GPU like a charm so take away the money from psu uprgade to Graphics card and tell the budget of your card

Sapphire 7750

Sapphire 6670

You can compare and contrast their specs to see which is better and for money value I'd prefer the 7750 even though its more expensive by 10 dollars than the 6670 on newegg.

Here's a calculator if you're unsure whether your psu is sufficient or not.

But IMO a 450~500 Watts PSU is sufficient for a single graphics card but if you plan on going dual GPUs in the future then buy a new one.
