why and by what margin is the ddr5 version better...??

is the ddr3 toooo bad and the ddr5 toooo awesome or both possess minor negligible differences??

will i experience enormous frame rate differences in the two of 'em in games..???
also try giving a plausible explanation for your answer...

because on paper, there is not a single difference between the two....
exactly same memory bandwidth,
exactly same texel rate,
exactly same pixel rate.....

the difference is about 40%...

as in, if the ddr3 version will get 20fps in a title, the ddr5 will usually get around 28fps

About a 20% difference between the two. That might not be a enormous frame rate differences in real time but enough to make the gddr5 a better purchase.

If you can skip the 6670 and move up to the 7770 or 7790 you will see that enormous frame rate differences.

Memory bandwidth is predicated on bus width and frequency and they both have a theoretical bandwidth of 64gb/s but both come no where close to that in reality.
