Video RAM and Screen Size

post #1 of 15
Thread Starter 
I understand that higher video memory plays an important role at higher resolutions, but how much does it affect performance on a single larger display? I searched the topic and found only one or two people saying that higher RAM helps with larger displays as well as with higher resolutions, so I wanted to make a thread specific to the question.

I'll be getting a 32" (1920 x 1080) TV for my system and also will be upgrading my video card. I'm currently deciding between a 69XX and a 570.

So my main question is whether the 2GB memory of the 69XX justifies getting that over the 570 for my choice of display. Because if not, then the 570 generally performs better than the 69XX and I'll be getting two free games with it.

Thanks for your time and help.

more ram only heps with higher reselutions, larger screen still has the same amount of pixels unless its a higher res.

i think the rule of thumb is if your screen is 1080p a 1gb card is fine, anything bigger you will most likely want to sli or get a higher ram graphics card.

Your tv screen is fine since it is 1080p, you wont see much improvement if you bought a two gb card so just buy one that fits your budget and overclocks well.

1 gig of vid ram should be fine. but u wont go wronge with 2 gig's either. screen size dont matter it the amount of pisels being used. the more pixes, the more ram u will need.

Size doesn't matter (that's NOT what she said) it's all about resloution.
@ 1080p, the 570/6970 is more than enough, until you start cranking up AA/AF.

(and you can always SLI/CF for more horsepower if you decide to go eyefinity/surround vision in the future)

At least with the 570, you've got physx out the box.

Yup, a resolution of 1920x1080 is 1920x1080 (or whatever resolution) no matter what monitor.
It does not matter if it is a 7" display or a 60" display, you graphics card just looks at the resolution.
If it lags on the 60", it will lag on the 7" at the same resolution (although it may be more noticeable on the larger screen).

Great, thanks for the quick replies.

570 it is then. Looking forward to OCing that monster. I may even sell the 9800GT then.

Nice avatar, mongoloid. You smell of elderberries.

This is why I laugh at people who **** on about their cool tv's lol.

My 22" 1650x1050 monitor has a much higher picture quality than my mates flash 52" 1080p TV lol.

1920x1080 > 1650x1050.

Although you can't really compare monitors to TV's.

What are you talking about? The fact that I won't need 2GB of RAM is the reason you laugh at people with large monitors?
