NVIDIA 750 ti 2GB Versus 4GB

[LeviMan91]

Hello, I am new to PC Gaming, and have a question. I am looking to upgrade my GPU, and with my current PSU the best card I can install is the 750 ti. I have found both 2GB and 4GB versions. Which is better for gaming? The most demanding game I play is Skyrim with mods, and would like to max out the settings / use graphics enhancement mods.

This is my current build:
Processor: AMD FX 4130 3.80GHz
PSU: 450w
GPU: GeForce GT 740 2GB
RAM: Patriot 8GB DDR3

Will I see much of a difference with the 750 ti? Or should I just wait and upgrade my PSU so I have better GPU options?

Thanks!

I might hold on for a system rebuild next summer with Arctic Islands/Pascal and Zen/Kaby Lake. The 750 Ti won't make that much of a difference.

Can you stretch to a 4gb 960? The 750 ti is ok, but the 960 would be a more significant upgrade.

I purchased my PC from CybertronPC, and when I called with questions about upgrading, they said with my current PSU, the 750 ti is the max. Can I use the 4GB 960 with my current PSU? Or are you recommending a PSU upgrade and then installing the 960?

Thanks

What PSU make and model do you have?

the 750ti is about 2 times better then that gt 740.

And neither card is fast enough to really use 2gb of vram let alone 4.

INWIN 450W ATX12v (copied/pasted from my order summary), I am still learning what info is relevant when I'm asked those kind of quesitons.

Ok, that should be fine with the 750ti and gtx 950, but i wouldnt go higher than a 950.

I've heard things like this before, what exactly do you mean? When considering GPU upgrades for my PC, is VRAM really relevant? What do I look for when it comes to choosing one, and how do I know if the new GPU is going to be particularly faster / more efficient?

This is the main thing I am having trouble with, in regards to comprehension about PC building.

Thanks for your feedback

Best thing is to ignore specs and rely on benchmarks.

Have a look at the Anandtech GPU bench, or Techpowerup gpu reviews and see how they perform in games, this is the best measurement in performance, the specs really dont tell the whole story.

VRAM is sorta important. it's mostly important when you don't have enough. the problem is one of thuroughput. how much information the GPU itself can process per time period vs how much information the vram can retreave, hold and send out in that same time frame.

In general the rule of thumb is the following

1gb VRAM is enough up to gtx660/gtx 750ti/HD 7850/ r7-265
-any more vram will yeild zero improvement in gaming no matter what the resolution/game. In short the gpu itself isn't fast enough to make use of more no matter what the situation

2gb VRAM is in a funny position, it's generally enough for gtx 760/r9-270x
-this is a funny number because the gpus start getting fast enough at this point that you CAN run into ram issues pretty quickly; just ask the owners of the gtx670/680 if they wish they had bought a hd 7970.

3gb VRAM is probably good enough for most of the cards on the market in 1080p resolution, and it's probably enough up through 4k for most cards with less power then the original titan,

4gb VRAM is probably the upper limits of what a single gpu card can use, even the limits for what one needs. very little benchmarks exist to disprove this, but when looking at 4k benches, it seems somewhere between 3 and 4gb is the sweet spot.

What throws these numbers into chaos is SLi/xfire. see in SLi/xfire the cards MIRROR their vram, so 2, 2gb cards won't have 4gb of vram to play with, they'll basically have 2gb. Since SLi/xfire almost doubles the performance of the cards in question, buying cards with a lot of vram for sli/xfire is a must. This is the reason there are 4gb 7850/r7-265 cards on the market. it's not because one of those cards can use 4gb of vram, it's because in xfire or 3 way xfire, the r7-265 can probably make use of more then 3gb of vram.

Sorry, but theres a bunch there that just isnt true.

1)The cards you list on the 1gb point have 2gb and can use all 2gb in games just fine...

2) I used a gtx 680 on 1440p no problem, no vram issues if you are sensible with what graphics options you use (or just let geforce experience to set them)

3) WTF? 3gb is just about ok for 1080, and also for 4k? Do you even know how much difference in pixels there is between the two?

4)... again, there is no limit to say a GPU "can only use 4gb".. Theres tons of people who have seen their Titans go above 4gb in certain games, its just generally the higher limit as very few cards have more than 4gb..

At least you got the SLI/Xfire vram mirroring right.

Find me a single benchmark ANYWHERE that shows a hd7790 or gtx 750ti performing better in ANY title with 2gb of vram over 1gb of vram (at same clock/memory speeds)

it doesn't exist. THG did an article about this just 12 months ago. simply put up until the hd 7850/r7-265/gtx750ti having more then 1gb of vram is pointless. Sure you can buy them with 2 or even 4; but it will never get an actual measurable performance boost from it.

I think you're misreading what i wrote. Same for each other tier i wrote about. You can become ram bottlenecked with a gtx770 in 1080p. There are benchmarks that exist which prove it.

On the other side of the equation, the few cards with 3gb of vram seem to be fine until you reach 4k, and are just fine in 4k with some settings turned down.

Meanwhile there isn't a title out there that performs measurably better in 4k with more then 4gb of vram. there really is only one card you can test this with, and they have. the r9-290x, it came in both 4gb and 8gb models. look for the 4k benchoffs with each running at the same settings. zero difference. in fact find the 4k benching reviews, many talk about vram utilization, and nothing really uses more then 3.5-4gb of vram in 4k.

that's not to say nothing WILL, but currently nothing does.

Is there even a 1gb version of the 750 ti? I dont beleive so, only the regular 750.
