Intro
This is intended to be a list of all of the GTX 780s that have been made. I will be expanding this thread based on feedback, such as overclockability, whether certain models have worse or better RAM, cooling, etc.

I will also try to identify if certain models suffer from coil whine, or other issues like if the manufacturers have downgraded the PCBs. Let me know if there's anything you want me to put in this thread. Also, let me know if any of these models do not come with VRAM or VRM cooling. I will add it in the notes.

Note: It seems like right now that there is a shortage of RAM and that a lot of the GPUs right now are coming with Elpida VRAM rather than the Samsung cards, including many of the "reference" designs.


What to look for in a GPU?
To begin with, if you are water cooling, the most surefire bet is to get a reference seeing that blocks already exist. Otherwise, you'll have to make a decision for a custom PCB based on the best ones available for watercooling and whether there is a waterblock available (unless you plan on using a universal core only waterblock with VRM and VRAM heatsinks).

Things you want in a non-reference GPU:
1. Good cooling: A good custom PCB should keep the temps cooler than stock and relatively quiet. You may be able to make a custom fan profile should you desire, in which case, look for the noise to cooling ratio of the fans.

Blower type coolers like the reference are good for multi-GPU configurations - they exhaust most of the air used to cool out of the case. Axial type coolers typically have 2-3 fans and exhaust some of their air out, but often most of the air back into the case.

Some custom coolers are 3 slot, which can be good for cooling (better temps at lower noise levels), but makes SLI harder and may affect the resale value.

2. VRM and VRAM cooling: A lot of the time, custom PCBs do not have VRM and VRAM cooling. VRMs especially can get extremely hot, hotter than the core even.

3. Quality of VRMs and Voltage Regulators: A lot of manufacturers will use custom parts for these components, which are very important. Certain manufacturers like to market based on the quality of their components.

4. A backplate and/or a brace. Modern GPU coolers are pretty heavy and a backplate or bracer can help prevent the PCB from warping, which may damage the PCB.

5. Overclockability compared to reference. Good cards will have better overclockability (some may be binned). I am unsure of the impact of voltage locking by Nvidia on this (will need to look into this for each custom GPU on a case by case basis). Most custom PCBs come with a small factory overclock, but that's not what we're interested in, it's the overclock that you are likely to realize if you apply additional voltage.

6. If you are going for 3+ GPUs, watercooling is generally preferred due to the heat output. However if you plan on doing so on air, I recommend blower type coolers as the axial type coolers really need to breathe.

Reference Card



This is the GTX 780 reference model. Naturally being the reference model, this would have water blocks. Cooler is identical to the Titans.

Cooling: Blower style, good for a blower, but so-so overall
RAM: Samsung K4G20325F0-FC03
Waterblocks available: Yes
Overclockability: Need more data (I'm hoping to get a range ex: 1,000 MHz - 1,200 MHz for each card). Default voltage lock seems to be 1.162 mV.

Other Notes:
No backplate or bracer
Voltage Controller: OnSemi NCP4206

Below I will list each of the manufacturers in order (let me know in the thread if there's anyone I missed with a custom PCB). Also let me know if any waterblocks come out for a non-reference PCB.

Asus
780 Direct CU II



Cooling: Direct CU II - 1 fan is intake and the other exhausts; there appear to be 2 BIOS profiles, 1 that cools at 14C cooler than reference (same noise as stock fan) and the other that cools at 9C cooler than reference but is 6db quieter) - see (http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_780_Direct_Cu_II_OC/29.html)
Waterblocks available: Not yet
RAM: Samsung K4G20325F0-FC03 (same as reference)
Waterblocks available: No

Other Notes:
Could be an issue with multi-GPUs seeing that one fan is an intake and a separate is an exhaust if you stack them tightly (ex: in 3 or 4 way SLI).
Comes with backplate and bracer to prevent warping
Comes with custom VRMs
2 models, 1 with a factory OC (GTX780-DC2OC-3GD5) and 1 at stock (GTX780-DC2-3GD5)

EVGA
GTX 780 ACX SC



Cooling: EVGA ACX Cooler - cools 7C cooler than reference, same fan noise; see (http://www.techpowerup.com/reviews/EVGA/GTX_780_SC_ACX_Cooler/30.html)
RAM: Samsung K4G20325F0-FC03
Waterblocks available: Yes - reference PCB
Overclockability: Need more data

Other Notes:
Frontal base plate to prevent warping (http://www.legitreviews.com/images/reviews/2206/evga-gtx780-acx-cooler.jpg)

EVGA has several models, varying from reference to ACX to their high end classified. There is also a "hydro copper" variant of this card offered.

GTX 780 Classified




Cooling: EVGA ACX Cooler - probably comparable to the ACX model
RAM: Elpida
Waterblocks available: ?
Overclockability: Need more data, but early on could achieve 1,400 MHz+ on air (http://www.overclock.net/t/1408710/cl-evga-gtx-780-classified-gets-overclocked-to-1410-mhz-on-air/0_100)

Reports seem to be wide, some models have a hard time making 1,200 MHz, to others than can clear 1,300 MHz.

Other Notes:
Custom PCB
Appears to have a custom phase design as well
Front plate present to prevent PCB warpage
It's a bit taller than the conventional PCB, so if you are using an SFF PC, make sure that you have clearance

There have been a few issues with this card:

Buying Guide
Right now among the cards, I would go with

High performance Overclocking
Galaxy GTX 780 HOF Edition
EVGA GTX 780 Classified
MSI GTX 780n Lightning

The Galaxy one especially is claimed to not cost much more than the stock one, so it's a good buy.

I don't know the RAM module yet on the Galaxy card, but if they're not using Elpida, then I would expect Galaxy to be the stronger overclocker.

It looks like MSI, the Galaxy HOF, and EVGA all have Elpida RAM. Price wise, the MSI one is going substantially above MSRP, but with EVGA you'll likely have to get EVBOT anyways, so it's hard to say. The Galaxy seems to be the cheapest of the 3.

In terms of raw overclocking performance right now, it does not seem like any card has a huge advantage over the other one. We still need to see a BIOS from MSI with the full 300%+ power limit and a full voltage OC though. I suspect though that most cards will be in the ~1,300 MHz range. YMMV depending on your luck with the silicon lottery.

Hopefully MSI gets that waterblock released soon though. The only other thing I think may be worth mentioning is that the Galaxy as indicated doesn't seem to have anything to prevent warping. That said, the MSI card is warping slightly under the weight of the cooler.

Quiet Operation
MSI GTX 780 Gaming
Asus GTX 780 Direct CU II
EVGA GTX 780 ACX

I should mention that people generally have regard EVGA's customer support well and Asus not so well in the customer support department. MSI is generally pretty good, although I have heard of a few slip-ups here and there.

Also, if you want quiet operation, you can make your own custom fan profile.

Just Gaming
Otherwise, if you're just gaming and have little desire to OC, then just go with the manufacturer that sells cheapest. I would consider the history of the manufacturer and their willingness to honor warranties though, so perhaps buy the cheapest that offers a good history of customer service.

Other info

I'm expecting to see custom PCBs from Colorful, ZOTAC, KFA, Point of View, and a few others.

I would also like to know what you would like added to this thread.

Right now, I'm mostly waiting for the custom PCB versions to all come out. The 780 Classified from EVGA and the 780 Lightning especially are of interest.

Usually only a handful of custom PCB cards tend to get water blocks specifically. Last generation, the 680 Lightnings and the 7970 Lightning/ROG Matrix did. I think it's going to come down to the volume of the cards sold.

Very true, but we only need one.

If it's the case, that mean you can use Afterburner and bypass voltage limitation.

It looks like it.

Other additions include high quality POSCAP capacitors with 2X longer lifespan and high current Coiltronics inductors. The PCB itself is a custom white substrate with 10 layers for optimum signal routing.
See http://www.galaxytechus.com/__US__/News6/NewsDetail?newsID=85 for details.

We'll have to see if MSI Afterburner works for it though. the problem has always been that Afterburner was designed first for MSI cards. It works well for reference cards of any brand and of course MSI's custom cards (PE, Hawk, and Lightning), but when you're talking other manufacturers, it becomes more iffy.

Galaxy in the press release though claims to have it's own software.

I'm impressed by this card though and I think it could give the other top cards some much needed competition. The diversity of the GTX 780 means that every maker seems to be coming up with their own unique solutions, many of which are catching up with the Titan.

Check out the Asus card as well:
