Is 2GB vram enough for 1440p gaming?

The9KGamer · Jul 25, 2015

The card I currently own is a gtx 770 2gb vram and I was looking for a bit of an upgrade in my graphics card so I could buy and use a 1440p monitor. The cheapest upgrade I found would be to buy a second used 770 which is around 200$ here vs a 390 or 970 which is about 400-500$ after everything. (Canada)

What I'm wondering is just how much would the vram bottleneck my performance at 1440p?

It depends on the game older games that didnt use much vram will be fine but any newer game the vram will be quite a bottleneck. ALot of new games now can use more than 2gb of vram at 1080p

Thought as much, because I want to wait for the new Nvidia line up to come out next year which is supposed to be a huge improvement but my 770 is starting to show it's age on some of the newer titles and I really would like to move on up to 1440p. Guess I'm either going to have to just wait it out or bite the bullet and spend some money.

Well honestly if we look at history because the 900 series is a new architecture the next nvidia line up will be overclocked rebadges most likely to maximize profits

VRAM has become a marketing issue.
My understanding is that vram is more of a performance issue than a functional issue.
A game needs to have most of the data in vram that it uses most of the time.
Somewhat like real ram.
If a game needs something not in vram, it needs to get it across the pcie boundary
hopefully from real ram and hopefully not from a hard drive.
It is not informative to know to what level the available vram is filled.
Possibly much of what is there is not needed.
What is not known is the rate of vram exchange.
Vram is managed by the Graphics card driver, so there may be differences in effectiveness between amd and nvidia cards.
Here is an older performance test comparing 2gb with 4gb vram.

Spoiler... not a significant difference.

I think a 1440P monitor is a great idea.
Buy one and keep your current monitor as a side monitor for email and performance monitors.
Such static use will not impact your gaming.
Yes, the added pixels that your GTX770 needs to manage will have an impact on fps.
You can reduce the impact by lowering the aa which is less needed for higher resolution monitors.
If all else fails, you can run some games in a lower resolution.
I would avoid sli in favor of a single stronger card.

@Firo I thought they were trying to come out with a new chipset every 2 years? http://www.notebookcheck.net/fileadmin/Notebooks/Sonstiges/NVIDIA/GTC2013/gdc2013_keynote_12.jpg

@Geo The whole point of the sli was to save money from buying a single card XD. Also that test is 3 years old now, most games can and will utilize a lot more vram nowadays will they not?
