I already have one MSI GTX 760 2 GB, but I'm considering to buy another(used) for 110 dollars. I already have big enough PSU. My biggest concern is VRAM, will it be enough for the next couple of years?

Is that well spent money or not?

EDIT: I'm gonna use it for 1080p 144 Hz

RIG:
CPU - i5-4670k
RAM - 8 GB 1600 MHz
PSU - Cooler Master V750 Gold

I think it depends how quickly you can save money. Having 760s in SLI will be good for a while, especially at 1080p, but the textures and AA will need to stay in check to fit in the VRAM.

If $110 is easily replaceable during the next year, go for it. That's a pretty cheap entry into a decent SLI configuration.

The upgrade from that would be the next top card, so maybe just keep it until you save about $600. Then, once the new top card comes up, snatch it up. You'll be good on that (and have more VRAM) until SLI or the next upgrade.

The games that don't use SLI either will be old enough to run on a single 760, or are so new that you can expect an SLI profile a couple months after release. The only other consideration is your...

The only other consideration is your CPU. It has to work a little harder to feed two GPUs. But if its new, you'll be fine. I'd say pull the trigger and enjoy :)

Updated my first post a bit.

VRAM could be a problem with GTA V and other future demanding games with that rig? But most games will run far better right?

Yeah, you'll be fine for almost all 1080p games. When VRAM is an issue (which looks like stuttering), then just lower textures and AA.

The 144 hz needs GPU power more than VRAM, so it will be a good setup to hold you over until you can afford a high end card in the next generation. Also, your CPU will work just fine with it.

The PSU, though, might be limiting. Having 750 watts may cut it with no overclock on the CPU or either of the GPU, but you'll definitely want more headroom on there. Check out this video on PSU wattage that came out yesterday.

Maybe, but I found this review

Total system consumption: 520 Watt. Should be room for plenty overclock there if those numbers are correct.

EDIT: Oh, 520 W is average power consumption during three games, but still. 750 W should be enough I think.

I currently run an SLI 970 x2 with a 750w PSU supply, but I don't overclock because I don't think it's worth my time, I already run every game I play on ideal settings at 4k at 60fps or greater.

It's worth it if you have a 4k 144hz monitor.

I'm not gonna squeeze the overclock to max, but the bottleneck with GTX 760 SLI is VRAM.

Could it be wiser to overlock memory instead of gpu clock?

Yeah, the 750 w will run the cards, but I'd guess that load will wear on the PSU, which will run a little loud under load. Without overclock, though, it's doable. Just something to keep an eye on.

As for overclocking memory, give it a try. But I think that the problem comes from pulling information from a slower source than VRAM. The path of information for graphics is this: HDD/SSD, RAM/CPU, VRAM/GPU, TV/monitor. For graphics, that's also the order of slowest to fastest information transfer. You get stutter during VRAM swap outs, not because the VRAM is slow to cear out unused info, bur because the system RAM is too slow delivering new info to the VRAM. So the card has to wait while that happens. It only takes a 10th of a second or so, but that turns into a noticeable s-s-stutter compared to the fluid motion (much faster) VRAM delivers.

Like I said above, though, just keep down the AA and textures when you get issues. You'll be okay.
