I got 8GB DDR3 corsair vengeance ram and this Christmas i want to buy a gtx 1070ti which got 8gb vram. So i was wondering if my 8gb ddr3 ram would be enough for my pc to run smoothly even with 8gb vram without any lag?

Yes, if you "need" more RAM, do not "add" 4GB to the 8GB you have now unless you know for certain that you can get an additional module that is exactly the same as (I'm assuming) the 2 x4GB modules you have now AND that your motherboard supports triple channel operation. If it does not, AND if it does not support FLEX mode, then you will want to either add another 2 x4GB matched set or, if you have only a single 8GB module installed you will want to add another identical (Or as absolutely close as possible, matching all specs for speed, voltage, timing, latency, # of chips and if possible one that uses the SAME type of ICs that your current memory used) 8GB module.

This is all so that you have compatibility for dual channel operation...

Depends on the games you are playing, but generally you want at least 16GB for a gaming PC these days. Your video card's VRAM is reserved more for graphical work and isn't used like system RAM.

I would consider getting another 8GB stick (making sure it's the exact same as the one you have) if you experience issues with high RAM usage (like using up 7.5/8GB of your RAM in game.

Yes, it should be perfectly fine. Most games, even the most demanding, don't use more than 4GB and Windows doesn't generally use more than 2-3GB itself. There are very few games that recommend 16GB of RAM and none that require it that I am aware of. The amount of VRAM really has nothing to do with how much system memory you need, but even if it did, 8GB would be plenty. If you find down the road that you do need more memory you can always find additional memory of the same model number or simply buy a new 2x 8GB kit, which would be the preferred method anyway to maximize the probability that all modules will play nice together and run in dual channel operation.

So yes, you should be fine for now.

Name one game that requires 16GB of RAM. There are some that might "recommend" it, but very, very few, and none that require it that I am aware of, so if you know of any, please post the names here.

I have 16GB of RAM in my current machine and have played about every game out there worth playing, including Star Citizen and never has my RAM usage ever gone above 8GB. Well, maybe once or twice, but only because I also had several high end applications running simultaneously, which most will not. I just didn't want to have to close those programs out at the time, but it was still barely beyond the 8GB threshold.

None. Windows 10 + its built in junk + a few applications + a new game gets you up to 6-7GB. If I'm building a gaming PC I don't want to have the chance of it laying into the page file. Not everyone closes down everything on their PC when they run their games. PUBG on 8GB of RAM would be rough I imagine.

I think, I learnt a rule of thumb somewhere a long time ago, that should work to cover your performance needs. Make sure you have at least twice as much RAM as you have memory on the graphics adapter. Some games can use quite a lot of RAM as a buffer for textures and other things. Also consider a lot of other apps and utilities are designed to be memory hogs themselves, so if you have the habit of multitasking with a browser open, maybe a media player and why not a screen recorder and whatnot running? It quickly adds up. Sure, the penalty for not having "enough" RAM might not be severe as it only adds the occasional load stutter. But, for a GPU the size of a gtx 1070 I'd definitely consider having more than 8 gigglebytes.
One alternative to help you conserve precious RAM for your games is to use Windows 10's game mode. That service will free up as much RAM as possible for you when you play games.

PUBG is poorly coded and is optimized even worse. Tends to happen with Indie games but it's not as bad as it was for the first while after release.

It should not use more than 8GB unless you are streaming or recording WHILE playing AND having several browser tabs open. Even then, probably not.

Even if it does, Windows 10 does a really good job of managing virtual memory and if you are using an SSD for the OS the effect should be fairly minimal, if it even needs it. 16GB is nice to have but I have not found myself using it at all on any games, like I said, even with some pretty hefty applications open.

Since RAM is SO expensive right now, it's probably a very good idea to get by with what you have and wait a few months for the supply to catch up with the demand after most the fabs were shut down for a period of time this year while switching for operational reasons due to most of them switching to a new process. I expect, and hope, that we'll see those prices start coming back down in the next two to three months.

That would mean that everybody with a 1080ti would need at least 22GB of RAM, and I can ASSURE you that 99% of them do not. There is no such rule that I am aware of, not even a common best practice that states such a thing. RAM configurations should be based on what games and applications will actually be likely to use based on the recommendations from the developer.

Gta 5 is one and bf1 is another that having 16gb is better off. Youll get away with 8gb but if you want less pagefile stutter get 16gb. Pagefile activity is only going to get worse the more vram is used and cant back it up with more ram.

Yeah. Adding 4gb ram will do i guess since the prices of rams these days are high on weed

Main RAM and GPU type do not have a direct influence.
GTX1070ti will work fine with DDR3 or DDR4 (platform dependent).
As if 8GB or 16GB or 32GB system RAM is enough or not, this depends on what you are doing and depends on the game, not depends on the graphic card.
For most cases, having 8GB is still enough for gaming only.
For some games , it is already recommended to have 16GB e.g. BF1. 8GB is the minimum...according to DICE.
Beside that, 16GB is recommended especially for those who do more and for those who wants a bit of a future proofing.
RAM kits were cheap...were, not are...they are not cheap anymore unfortunately. This is the problem.
I would try to live with 8GB for now, if you see issues, try to add another 8GB, if possible...if everything works fine, leave the 8GB as it is.

Yes, if you "need" more RAM, do not "add" 4GB to the 8GB you have now unless you know for certain that you can get an additional module that is exactly the same as (I'm assuming) the 2 x4GB modules you have now AND that your motherboard supports triple channel operation. If it does not, AND if it does not support FLEX mode, then you will want to either add another 2 x4GB matched set or, if you have only a single 8GB module installed you will want to add another identical (Or as absolutely close as possible, matching all specs for speed, voltage, timing, latency, # of chips and if possible one that uses the SAME type of ICs that your current memory used) 8GB module.

This is all so that you have compatibility for dual channel operation which doubles the memory bandwith throughput. Not operating in dual channel will have a appreciable affect on your system performance, so it's best whenever possible to try and make sure you are setting yourself up to able to do that.

If you cannot, then as I said before I'd ride it out with the 8GB you have now until you can save enough to simply BUY a single matched set with 2x 8GB that is already tested to work together in dual channel.
