Okay...suppose I have GT 440 or GT 630..how much more power will be needed for the same graphics card model but for 2GB size? Will the 2GB version need significantly higher power?? PLZ help

The GPU's memory will change the power need by about 10 watts but if you are using any monitor smaller than 1080 than you probably won't need 2GBs and you could save some money.

The power need between 1gb and 2gb cards is not that great so I would go for the 2gb version as new games are need more and more ram anyway and that requirement is only going to go up in the future.

No not really.On cards this low end even 512MB will be enough.Also the 2GB memory is likely to have a higher latency which will make the card slower.If you can find a 512MB card buy it.Otherwise 1GB is the way to go.
