I have a single GTX 780 HOF. It retails for 689 in the states but 719 in canada (729 on ncix), the classified retails for about 699. The classified isn't that great in SLI because of how hot it gets. The ACX cooler simply isn't strong enough to cool the card efficiently (1.35 volts is monstrous!). Also there is not really a point buying it over any of the other cards considering how almost all are now capable of overvolting to 1.363v using the afterburner hack and the other overvoltage mods. The HOF is a massive card. 2.5 slots to be precise so sli is kinda hard to do without a slot between them. The pros of having a larger cooler is that it stays much cooler (obviously lol). OC'd to 1306 @ 1.26vots I was in the lower 70s and the fan speed wasn't all the way up. Basically any non reference or non watercooled card gets uber hot in SLI. Especially 3 fan designs. 7990 crossfire for example is near impossible because the top card reaches temps over 95 degress celcius (a single 7990 is a great deal though!). So the lightning would probably be bad when in SLI. I would go with the hof. It seems like the perfect mix between performance and cooling right now.

About the classified SLI---I don't know if this is an anomaly, but one user reported idle temps of 50 degrees celcius for his top card.

Edit: If this is going in you "If I win" rig, then yes, go with the HOF (because you have enough slots on your board). Another bonus of going with the cards I mentioned is that they are binned, meaning only the best are selected to become these models. The EVGA ACX line aren't binned, they are reference cards.

The hof seems like a fantastic non-reference 780, but something I am not really looking at doing because I prefer to go EVGA with my gpu's for their awesome customer service. Hmm that is terrible idle temps

If you're going SLI I would consider going reference blower cards since they don't dump hot air back into your case. Considering if your comfortable running 1.3v on a reference card you can do that as well with the latest version of MSI AB. There are memory hacks that also allow even greater voltage as well. I'm personally waiting for the lightning before I buy another 780.

Also if you are not planning to watercool then I wouldn't even get the classified. Reference is fine. The classified is great because it allows voltages up to 1.5v. At really high volts temps also get high so to really utilize the classified's full potential you would need to watercool or ln2/dice. If you have plans to just use the stock cooler than just go with a reference design 780.

Dang! Good point with the temps as this build will never touch water since my custom loop would be over $1k, and that is to much considering what I already put into the rig.

Yes, you are correct. Also, they only allow reference designs in their step-up program as strong island pointed out which sucks!


So I guess I will just settle with the sc version, now in a sli setup with my config should I go acx or blower? I undestand the acx is cooler, but the spacing between the cards is going to be tight since I'm using the vi hero, so will my intake fans in the front be able to remove the heat produced by overclocking fast enough, or will the blower benefit here?

They both have 3 year warranties and US toll free numbers.

As soon as I submitted my response to the earlier posts I read you comment haha. I really won't overclock the cards from the start since I want those cards to last as long as possible, but when performance starts to become an issue I will squeeze them as hard as I can before heat becomes an issue.

The lightning is going to be sick! Just not a fan of a yellow fan lol tongue.gif Very expensive with some estimates at $750, but we shall see!

Go with the reference cooler if space is tight. The advantage the ACX has over the reference temps wise does not apply to SLI. They are both non binned so performance is more or less equal.

If you are not overclocking seriously there is little point in getting the Classified from EVGA. The card is aimed at high overclocking and benching. You will pay for tech you won't use basically.
The stock card overclocks well enough and performs great.

EVGA warranty is now a price. 3 year standard with the card, but you can purchase an additional up to 5 years of warranty. Kind of cheesy but not horrible I guess. Additional 5 years I think is $30.0 after you register the card.

That was what I was thinking as well.

Upgrading the warranty is a bit strange, but everyone wants their tech to last a certain amount of time. Some more than others lol. Somebody recently posted somewhere about buying the extended 10 year warranty for their gpu and I was thinking that his gpu would be sooo outdated by that point lol.


Thanks guys for all the help I will be purchasing the 780 sc blower style gpu since it seems like the better bet along with being available now! thumb.gif
