I just saw the 7970 Lightning but there was No HDMI on it! Why is it? Also with an adapter will I be able to get the same performance as a HDMI?


This is because, in the grand scheme of things, HDMI is no longer the "top" output. Everyday HDMI is limited to 1920x1200, while both DisplayPort and DVI-D can output 2560x1440. Also, while the 7970 Lightning has 6 outputs, you'll notice that only 2 are DVI-D. This is because Eyefinity requires all displays beyond the second to be driven by DisplayPort. If you have a third monitor that doesn't have DisplayPort you need an active DisplayPort to HDMI/DVI-D adapter to output it with any Eyefinity enabled card.

Edit: looks like I haven't looked at that card in a while. Both DVI ports are single link, meaning they can output the same resolution as HDMI. DVI-D means that you have digital only (so you can't output to an analog [most commonly VGA] monitor through an adapter) while DVI-I has both digital and analog outputs (so you can use an adapter on that one).

Does this work without any hassles? http://www.aocindia.com/product.php?product_id=22&type=...

also I hope the repsonse time dosent meddle with my gaming?


That monitor supports DVI-D input, so it will work as long as you are only ever planning on having two of them (or else buying active adapters @ $80/ea)
The response time is a bit slow, even for an IPS panel, but it shouldn't have too much of an effect, it will only ever be truly noticeable online when your ping is below 14 ms (single player wise it might be noticeable, I don't have enough experience with that high of a response time to give you a definitive answer).

Hard to say. I would say that it will blow things out of the water now but in the future as it still may be useful as one would suspect that in time you will have to turn down settings how much its hard to say but I can't imagine a ton over 2 years more so in 3.

I'm just trying to say that over time you may have to turn settings down in games. However your card should be good in a few years however there is no such thing as futureproof so just something to keep in mind.


Yeah I guess. But for example BF5(assuming it releases somwhere in 2015) can I be able to run it on medium to high settings?

We can't know that-how are we supposed to know that?? There's not even a BF4 at the moment and you're asking for the game after it??

that being said, an msi 680 lightning oc'd to 1600+mhz on water cant be messed with by any 7970, even on water.


I don't understand this comment, as it's neither particularly relevant nor correct. For one thing, neither the 680 nor the 7970 will do 1600 MHz+ on water - not even close. I don't even believe there's one golden chip out there that will do that stable. For another, the 7970 is not only the better overclocking card of the two lightnings since it has out-of-the-box software voltage control, it also holds most of the overclocking records - not its 680 cousin.

Anyways - I think earlier some folks were confusing the difference between DVI-I and DVI-D with the difference between DL-DVI and SL-DVI. The only time the output configuration of the 7970 Lightning is a problem is if you want to use a 120 Hz 1080p monitor which does not have a DisplayPort input or a 2560x1440/1600 monitor which does not have a DisplayPort input, because in those cases you need DL-DVI. It's not as big a problem as you might think. It can drive any 1080/1200p 60 Hz monitor just fine and it comes with a handy dandy mini-DP to HDMI adapter. DVI-I or DVI-D doesn't really matter. What matters is if Dual Link DVI is needed or not.

If you're not planning to overclock, I'd say get the 7970 easily. If you are planning to overclock, it's mostly a question of how much risk you want to take. When both cards are OC'd to ~1150-1200 MHz, performance between the two is very similar. However, average overclocks are slightly higher for the 7970 and starting clocks are also a bit higher - i.e. it's less risky.
