I got an e-mail from the forum to redefine my query as it was not yet answered.So, i am posting this short question after thorough researching on the net.After researching enough, i decided finally to go for either of these cards :-

Nvidia Geforce GT 620
XFX AMD Radeon HD 5450

Both are safe to use with my 300W PSU(actually, i don't want to upgrade my psu at present),
but my question is - of which capacity, 512 MB or 1 GB. Does memory of GPU has to do anything with power ?

Thanks ! :)

You're most welcome! Glad I could help :)
The size of the memory does not have to do with power directly. But depending on the resolution you will be gaming on, it might be a problem. Considering that these cards are pretty basic, they will not be able to handle 1080p with AA anyway. That means you'll be gaming at a significantly lower resolution, which means 512MB should be more than enough.

The amount of memory available to the GPU dictates how many colours it can display, and how high a display resolution it can manage, so more is always better. 512MB just doesn't cut it these days with large-screen LCD monitors now being widely used which require high resolutions from the GPU. Get nothing less than a 1 GB card.
Even that isn't enough if you are a gamer.
 
Memory does not have to do anything with power. But yes you'll need some VRAM for the GPU to compute and some for the resolution.

Simply put, 1 GB is a good enough amount to handle both for the basic cards, your cards are pretty entry level, I'd still say go for a 1 GB version as the price hardly varies for those and you'll get more VRAM to get some more space while buffering, loading, etc.

1 GB GPU the answer is :)

AA stands for Anti Aliasing, a technique used to add greater realism to a digital image by smoothing jagged edges on curved lines and diagonals.

"AA" stands for Anti-Aliasing. If you don't know what that is its a digital graphics feature that reduces jagged edges on any angled lines being displayed.

Thanks Again !! Sir :)

 
I respectfully disagree :) Those cards can barely put out 20 FPS at 1080p. Considering that Skyrim at Ultra quality only uses 800MB at 1080p, lower resolutions combined with lower settings will not really reach the 512MB.

Obviously the price plays a role.
Same price -> 1GB.
Price difference too big -> 512MB.

But if the 1GB makes you feel safer, go for it.
