To give you an example of how much DDR3 vs GDDR5 is, this review uses DDR4 (faster than DDR3) & GDDR5 and DDR4 was 55% slower.

It’s actually getting system memory on it, which is a tremendous downgrade. The memory bandwidth reduction is several-fold, dropping from 48GB/s to...

For actual gaming cards, don't get anything below a GDDR5 card, preferably one of the newer GDDR6 cards.
