Hello :) 

I currently own 1 Gigabyte GTX 660Ti OC (GV-N66TOC-2GD) and I'm thinking of
upgrading my system to a 3 screen layout (Dell U2312HM).
for that I'm going to need a hell of a system, and I can't decide what should I do!

Which would you recommend me to do?
Buy another GTX 660Ti and perform an SLI?
OR
Get the new Gigabyte GTX 770 OC 4GB (GV-N770OC-4GD) and use a single card layout?

I'm talking about pure performance. What will give me the biggest FPS boost?

Worth mentioning: I know the GTX 780 is a real beast, but I have no money for that so this is NOT an option.
Please do not recommend that.


Thank you,

You will need at least 2xGTX 770 for a good gaming experience using 3 screens.

so yes get one GTX770 4G now , and when you can buy another one , do it and SLI them.

2x GTX 660ti is slow for 3 screens gaming.

and you will need more memory as well , so 4G is better.

btw , 2x GTX 660 ti in SLI does not mean 4 GDDR5 , it means 2 GDDR5 in SLI. you don't add them up. they stay as 2G cards...

Thank you! Got many more questions now..

- Can 1 GTX 770 handle 3 screens gaming when quality is set to medium?
- Do you know any other companies that manufacture 4GB GTX 770 cards?
Perhaps with a better cooling system?
- What does the system do with the other 2GB GDDR5? Just ignores it?

Thank you :)

1- depends on the game. but yes you can play in Medium/low settings.

2- here you go :

- Inno3D GeForce GTX 770, 4GB GDDR5
- Gainward GeForce GTX 770 Phantom, 4GB GDDR5
- Zotac GeForce GTX 770, 4GB GDDR5
- Gigabyte GeForce GTX 770 WindForce 3X OC, 4GB GDDR5
- MSI N770 TF 4GD5/OC Twin Frozr Gaming, GeForce GTX 770, 4GB GDDR5
- Inno3D iChill GeForce GTX 770 HerculeZ X3 Ultra, 4GB GDDR5
- EVGA GeForce GTX 770 FTW ACX Cooler, 4GB GDDR5

3- They share the SAME frame buffer , in other words each card has a copy of the same data.

Thank you for the detailed answer!

Which card would you recommend most, and why?

I like the Gainward Phantom the most. but it has one drawback , It is a three slots card.. so SLI would be a problem for some cases and motherboards.
it has very silent REMOVABLE fans , and good cooling.

MSI are good as well but I prefer the Lightning and it is not released in 4G yet , just 2 G .. it is the fastest overclock around with 2 huge fans and they run in two directions to remove dust from card.

EVGA are well known. but I never tried one to judge it.

you can as well buy the cheapest one and order a cooler for better than all , but the better cooler is around $100.

(I'm sorry it took so long, I'm serving in the army)

I've checked them all and from what I've seen, the Inno3D has the highest clock speeds
1150MHZ / 1202 MHZ (Boost)
http://www.inno3d.com/product/ichillgtx770_4gb.html
EVGA Also has it clocked to 1150, however not seeing Boost speeds (what is Boost anyway?)
http://eu.evga.com/products/moreInfo.asp?pn=04G-P4-3778...

All of the other cards have lower clock speeeds:
Zotac: http://www.zotac.com/products/graphics-cards/geforce-70...
Gigabyte: http://il.gigabyte.com/products/product-page.aspx?pid=4...
Gainward: http://www.gainward.com/main/vgapro.php?id=915&lang=en
MSI: http://www.msi.com/product/vga/N770-TF-4GD5-OC.html#ove...

There is also this versions of Inno3D:
http://www.inno3d.com/product/ichillgtx770lcs_4gb.html
This is clocked the most, has more Texture Fill Rate and more Memory Clock,
However, I'm not sure if this fits to SLI, if this cooling is easy to handle, and don't know the cost.

What do you say?

Thank you,
Omga4000.

I would go with evga period, I know they are a little more expensive but they are completely worth it. I've bought zotac, galaxy, MSI (the worst IMO, they jigger their clock speeds up and actually had a huge batch of faulty cards) evga has great support for returns and all that stuff. And boost is pretty much a gimmick meaning when your card needs the speed, it temp oc to a certain speed. But don't buy one brand over another over a minor 100mhz GPU clock, the mem clock is more important and u can use MSI afterburner or evga precision x to get 100 MHz. I prefer the blower units just because I do sli and don't want the heat blowing on my over card and in the case, they run pretty cool anyways, my gtx 660 ti sli setup oc'd stay around 60-60c so they don't get too hot anyways. But out of all the cards I've purchased, I prefer evga by far

Also, two 660 ti's kill a 770, I'll find the link for the benches and post it
