gtx 760 2GB 2 way SLI vs gtx 760 4GB 2 way SLI which is better for 1920x1200 resolution

ramkumarfx · Aug 21, 2013

for future proof 2GB sli is enough or should I get 4GB cards..

I will use only single monitor (1920x1200)
I heared that some games need more than 2GB

Unless you plan to game at 2560, 2gb is fine for 1920. However, if it was me, I would buy the best SINGLE solution card you can afford rather than putting up with potential driver/sli problems.

Games use no more than 1500MB or so currently.

Check out the video where some guy does tests on how much vRAM is actually in use during some demanding games.

The 4gb version is completeley unnessary, 2gb will be more then sufficiant at 1080p. If you were going dual or tri moniter config I would recommend the 4 gb version

To answer your question, 2gb vs. 4gb is a performance issue, not a functional issue.
The difference is minimal. Here is a report on that:

I would prefer using a single card where it will do the job. Here is my canned rant on planning for sli:
-----------------------------Start of rant----------------------------------------------------
Dual graphics cards vs. a good single card.

a) How good do you really need to be?
A single GTX650/ti or 7770 can give you good performance at 1920 x 1200 in most games.

A single GTX660 or 7850 will give you excellent performance at 1920 x 1200 in most games.
Even 2560 x 1600 will be good with lowered detail.
A single gtx690 is about as good as it gets.

Only if you are looking at triple monitor gaming, then sli/cf will be needed.
Even that is now changing with triple monitor support on top end cards.

b) The costs for a single card are lower.
You require a less expensive motherboard; no need for sli/cf or multiple pci-e slots.
Even a ITX motherboard will do.

Your psu costs are less.
A GTX660 needs a 430w psu, even a GTX780 only needs a 575w psu.
When you add another card to the mix, plan on adding 150-200w to your psu requirements.

Even the most power hungry GTX690 only needs 620w, or a 7990 needs 700w.

Case cooling becomes more of an issue with dual cards.
That means a more expensive case with more and stronger fans.
You will also look at more noise.

c) Dual cards do not always render their half of the display in sync, causing microstuttering. It is an annoying effect.
The benefit of higher benchmark fps can be offset, particularly with lower tier cards.

d) dual card support is dependent on the driver. Not all games can benefit from dual cards.

e) cf/sli up front reduces your option to get another card for an upgrade. Not that I suggest you plan for that.
It will often be the case that replacing your current card with a newer gen card will offer a better upgrade path.
The Maxwell and amd 8000 series are due next year.

You need to make your rant a sticky on the forums - great info and reasoning!!

I want to do sli later i.e 2 or 3 months later.
Now i want buy single card gtx 760
I read somewhere in sli configuration vram won't stack but performance improves and when vram is not sufficient performance automatically decreases if that's true......... my question is when I do sli each card 2gb vram is sufficient for increased performance or should I take 4gb cards for my 1920x1200 resolution
Please make me know real facts if i read wrong information.........
Now i dont have enough money to buy single high end card thanks for the all replies

vram from two cards in sli is not additive.
If you read the link earlier, you would see that 2gb or 4gb is not a noticeable performance issue either.
When you go for sli, you are trading better synthetic benchmark fps for more inconsistencies and stuttering in actual gameplay.
Nvidia seems to do a better job of minimizing this compared to amd today.
Pick your poison.
I might wait until you can pay for a GTX770 2gb which will be very good for 1080P gaming.

Then gtx 760 is not enough for games like crysis 3 i am not expecting more than 40 fps
