People who are comparing with 970/980
Didn't we have the 290/290x for that? Which are the same cards?
But in the case of R9 390 4GB vs. 8GB, what matters is having at least 4GB of VRAM over 3-3.5GB, not necessarily having 5-8GB. In that case 390 4GB seems like a smart choice to save $ on and invest it towards an SSD, CPU cooler, better PSU, better CPU, etc.
I got one better for you, pay $10 less for
GTX960 4GB to lose almost
19-30% of the performance against the $210 R9 380X.
If we are talking saving 30$ to invest on a different part, it's not really much of save. Ok I am not one without budget restrictions, but I still cannot see how losing half the video ram, will do any good on the rest of the system. I mean it's 30$. Essentially peanuts compared to the total system cost.
those who are smart enough to realize that 4gb is plenty of vram for a single gpu. even 2gb is sufficent. especially when enjoyable frame rate is taken into consideration.
that 10% could be used toward something else more beneficial.
Where's the smartness when you lose half the frame buffer for 30$?
Have you seen how games utilize video ram nowadays? I am not saying that they actively need more than 4GB to render high textures with high settings, but they can easily use excess video ram to store important data that will be requested later.
In any case, if someone is buying Hawaii, I don't see the point of not opting for the 8GB model, to give himself some future proofing.
Some people may think that such a card will run out of gpu power long before it runs out of vram. This may turn out to be true. I believe we have all seen that the most important setting that makes a game ugly, is the texture quality setting. Something that affects video ram usage directly. Why would someone want to risk that for 30$?
People who feel that 50% less video ram diminishes the overall card by less than 10%, duh. Some people may think that the card is going to use more than 4 GB, and that's worth the extra. Some might not, and to them, why pay 10% more for a nearly 0% increase in performance? A video card's value is defined by framerates, not the BoM.
I cannot disagree with that.
Everything is down to what each one feels. I feel that it's not worth to save that 30$.
That does not make me correct. Same goes for that other guy that feels different.
If the are looking what they are getting now, with no thinking about the future, sure go ahead and sacrifice that extra 4GB. Speaking for myself I wouldn't, even if I am on a 18-24month upgrade path for gpus. People with longer upgrade periods should future proof themselves.
