I will be playing games like modern warfare 3, black ops 2, bf3, gta 4,crysis 2, splinter cell blacklist, hitman absolution, tomb raider etc.
I'd like to play on highest settings, with AA and AF if possible with this card: http://www.alza.sk/gainward-gtx650-1gb-ti-boost-golden-...
I won't go with the 2gb one because it's much more expensive (30 euros more). Please don't recommend other cards, I know all about the hd 7850, the gtx 660 etc.

More about : 1gb vram 1680x1050

Having the extra 1gb of vram isn't going to have much of an impact in performance even if the game uses it.

Can't find any articles to show it, because it's pointless to make an article on this.

But if it runs out of vram, it will cause very big fps drops and stuttering if i know correctly...
So back to the real question, will 1gb of vram be enough for THIS EXACT CARD and THIS EXACT RESOLUTION?
for example a hd 7870 doesn't need 4gb because it will run out of processing power way before it runs out of vram, so 2gb is enough for it
so is 1gb enough for this card? (gtx 650 ti boost)

No, if all the vram is used up your frames will not take a sledgehammer to the face. I you're paranoid just get the 2gb version.

Do you have any experience with that situation? (when the gpu runs out of vram)

Yes, on my old Palit HD 4870. When I added high resolution texture mods to Skyrim, performance didn't take a significant hit. Only problem was some texture popping as high res textures take longer to be drawn.

When it comes to the usage of RAM in a GPU, the sheer amount of pixels being rendered at any given time is what's important. The GPU needs RAM to keep all of that data for rendering the pixels, which is the reason that running a multiple monitor setup needs 2GB+ of RAM in order to be functional and fast. A card with 1GB of RAM will comfortably run up to a single monitor at 1920 X 1080 resolution. A single monitor at 1680 x 1050 will be absolutely fine for a 1GB card.

Spring for the 2gb version tomb raider uses close to 2 gigs at some points in the game with highest settings

The extra 1GB of video memory will not bring any performance benefits, however when your VRAM is overflown you will experience a lower minimum framerate whereas the average and maximum framerates you experience will be no different

Given that you mentioned that you want to run these games on Ultra with AA and AF (which will further increase the amount of memory you use), it'd be best to get a 2GB model

It depends on the game but games like Crysis 3 on high settings utilize around 1.2-1.3GB at 1680x1050

I think i will stay with the 1gb model, it's a much better deal, if accidentally the 2gb one gets a better price, i will jump on it. Thanks for all your help folks :)
