By the looks of it, you might be choosing two entirely different GPU's. Which ones are you comparing?

The type of memory does not indicate performance level of the card, at all.

still many threads and replies testify the fact that gddr5 should be preferred due to greater bandwidth reating to better performance!

The performance of a video card is dependent on several things including but not limited to GPU type, game requirements, and memory type. However, of those three the memory type is generally the last thing to consider. While GDDR5 is faster than DDR3, the comparison really only makes sense when all other things are equal. in that case GDDR5 is preferred because the higher bandwidth during memory transfers allows the GPU to be actively rendering images more often resulting in better framerates. However, the difference when using different GPU's is not easily quantifiable due the fact that the GPU differences are contributing to the variation in performance.

Look at the performance between the cards, not specific components inside them. Just going purely on the model number and how new the architecture is, I would guess that the 630 is better.

I agree with the others, at this extreme low end, the limiting factor will be the GPU, not VRAM.

Understand that all things being equal, GDDR5 has the possibility of performing better than GDDR3. But on different GPU's, all things are NOT equal, and the type of memory used is no indication at all of the cards overall performance level. You need to look at some benchmark charts of how the card actually performs running the games or programs you intend to use, that is the only way you can determine performance level or differences in cards. And since you have a couple of threads going here on this same subject, I'll add that all PCIe type cards are backwards compatible with all PCIe slot versions. Do not worry about that either, just pick the card that performs as well as possible within your budget. Use the GPU charts here on Toms Hardware to help you with your selection, and also check out the monthly "Best GPU for the money" articles, they are pretty good to get a overall impression of a cards performance level at particular price points.

so if i get a zotac gt 630 ddr3 instead of gt 630 gddr5 what will be the fps drops..??/

thnx for the input guys

@jitpublisher thnx for the replies... but gt 630 is a card that fulfills all the criterion
1.fits my budget
2.pcie 2.0 ( my mobo has got issues with 2.1)
3.power supply

Since the GeForce GT 630 is just a rebranded GeForce GT 440 this review will give you an idea of the performance difference:

@dasilhelm combination of budget an other problems lead me to select these cards .. otherwise i would have gone for 7750
