I have researched this quite a bit and can't find a very good answer. Will a DDR3 VIDEO card get much worse performance than a DDR5 card of the same model? Sorry if this gets asked alot... I couldn't get a good answer elsewhere. Thanks!
Based on my memory, I believe going with DDR3 results in about 7% - 9% lower performance. Therefore, it's better to go with DDR5 RAM unless it carriers a premium that is far higher than you are willing to pay.
