SLI 9600GT 1GB with another 1GB or 512MB?

post #1 of 49
Thread Starter 
I currently have the 9600GT from PALIT thats 1GB, 700/1000MHz, and i want to SLI it with another 9600GT, but my question is, should i get another 1GB card or go with the 512MB one? what would be more better and effective?

Why get the 1GB card... It has almost no preformance gain over the 512MB card.

And you would have to get an identical card, I.E the 1GB card.

a 9600 cannot use a full 1gb of memory to its fullest.

yes hes right, you need 2 identical cards for sli.

sell the 1gb, and buy two 512mb 9600gt cards.

Quoted for truth.

TR did an article where they tested a ATI 3870 with 1GB of RAM on it... Nearly identical to the normal 3870, even at super-high resolutions.

And ATI has better memory management, so Nvidia won't use 1GB, not even close.

I've "heard" that Nvidia is working on drivers that will allow different cards to work together.

Until then, you should definitely keep your cards matching.

As for whether or not there is any advantage with 1GB over 512MB, I'll have to disagree- sort of. With most games available now, it is true there isn't any advantage. But it is related to the game engine, not the speed at which RAM transfers info. Whether or not the GPU can keep up any extra info still depends more on the engine and what you are doing with the data than the GPU.

The compelling part of 1GB is that as new games come out, many of them WILL take advantage of larger memory spaces. So a year after you buy your card, you will start to see some differences.

Age of Conan already takes advantage of 1GB of RAM. By having more memory you can extend the draw distance for high res textures. The extra memory effectively acts as a buffer which improves your frame rate since you don't tap the hard drive as often. It also makes things look better.

As you turn on the bells and whistles, the performance improvement increases.

Would a faster or more powerful GPU do all this better? Obviously. But you can only put off buying a card for so long waiting on newer and faster GPUs.

My advice is that if you're going to keep your graphics card for more than a year or two and you want to have every advantage available to play future games, you should definitely go with the 1GB. If you change your video card every year, then it makes more sense to go with a 512MB version.

this is exactly what i was thinking in mind, thank you, everyone else is so against having 1GB video card that i just dont get why, but i agree with your explanation completely, maybe not now but in the future as newer games come out, i'll be ready, and to SLI it with another PALIT 9600GT 1GB RAM, i will be ready with 128 stream processors, 2GB RAM, 700core x 2 and 1000memory x 2, im gonna overclock both cards to 751\\1106 when i have them in SLI mode and i will be prepared to play the new games that come out, and i only need 1280x1024 resolution anyway, i only have a 17" screen, and for me, thats more than enough, its clearer than a blind man's vision after Lasik surgery, i get phenominal frame rates with just this one 9600GT, in GTA: San Andreas i get 137FPS, and Crysis right now i get around 30-40FPS on High settings on 1280x1024, and Far Cry, on Very High settings and water set to Ultra High, everything maxed out at 1280x1024, i get 60-80FPS, so i cant really be mad, the games run smooth like no tomorrow already, i cant wait to see what SLI will look do for FPS
