Is a >1GB Card Necessary...

post #1 of 30
Thread Starter 
Pretty keen on getting this card.

If I will be running dual monitors but only gaming on one at full 1080p (the other will probably just have the desktop or browser, nothing intensive). Would a 2GB card be necessary? I've already started my build but have not ordered the GPU yet. Is a 2GB or 1280MB card absolutely necessary if I will only be gaming on one monitor?

ps. Probably won't OC any further, 950mHz factory OC should be sufficient (I don't think I'll bother try hitting 970mHz/1000mHz/1gHz without further cooling).

Is it "necessary"? No. I would recommend it though. You would see a bit difference in performance. Also, if you ever upgrade monitors the 2gb gives you better performance on larger resolutions. Point is the 1gb card will work fine for you.

Over 1GB cards are only vital for multi-display gaming. Having a second display idling at the desktop while gaming on the other doesn't count.
If you game at high resolution, (well over 1080p) then it will be needed, but for a single normal or low resolution screen? It's not needed.

Probably not necessary, but as fastsite mentions, it can't hurt to have it. I've used over 1GB with high-res textures on Fallout NV and Oblivion at 1080p, if that's relevant.

As previously mentioned, for higher resolutions, you will need the extra vram. You'll be ok with that card for a time though. While playing Crysis 2 at 5760x1080, I sometimes use >2.5gb of vram! That's insane, but then again, it is a demanding game. Enjoy your new rig!

1Gb will be more than enough good sir

Based off of what MSI Afterburner tells me about the games I play, I would certainly consider getting a card over 1GB, especially at 1080p. I game at 1680x1050, and maxing out some games can easily take over 1GB of VRAM, namely the prettier looking games, like Crysis 1 & 2 (2 I use an average of 1500MB), Metro 2033, BF3 (average of 1400MB), even Batman: AA with the Physx maxed can take over 1GB.

With that being said, I don't know how much system performance will be punished if you do run out of VRAM, but now that you're looking into buying a card, I would at least consider it, or ask people who already have a card with 1GB of VRAM that game at the resolution you do how performance is and how often they run out of VRAM.

Well it really depends on the games you play an the settings you want to use, in games like Crysis 2, Metro and BF3 if you want to up the AA you will need it since those games eat a lot of vram but for other games will not be needed, if you want to up the AA go for the 2gb or a gtx 570 (EVGA) if not the 1gb version is more than enough

Hmm okay thanks for the help. I was hoping for playing BF3 at a minimum 60FPS and since I don't want to sacrifice too much graphics for performance. I'll try compare the GTX560ti 2GB and the 2GB 6950 (maybe the new Sapphire to unlock), and see which would be better. If it's going to exceed 1400mb VRAM it may be worth 2GB. I think I'll go with the 560ti though. With the amount of 3D work and OpenGL rendering it may be worth going for nVidia. The Cuda Cores help a lot with 3D rendering from what I've read. Thanks!

It's not 100% necessary but I seriously recommend it, it will add life to your card and it isn't that much more expensive. Some games with high textures can use over 1GB even at 1080p.

Enjoy your new machine
