nVidia Dual GPU Cards

[Sam DeathWalker]

25 boxing on one computer isnt what we were talking about. 10 Boxing is what we were.

You have no links to any of yur assertations.

You seems to think that you will get double the performance with 2 gpu as you would with 1 gpu simplly because you are 5 boxing.

Most of the time the 2nd GPU seems to add like 30 percent increase, on single boxes.

You have a single buss. If you have to feed data to two GPU yur buss is twice as busy. Ya if all the data is avalable to both GPU's the instant they need the data for the next instruction you will get substaintial performance benifit but that just not going to happen at all in real world applications. Even a single GPU if all the data is available when needed will blaze though wow. It not how fast the GPU returnes the result of that instruction, its how fast that the data is available for that instruction after the last instruction is completed. And having two gpus dosnt help that much at all.


If the gpu's cannot access the other gpu memory space you have to load the SAME TEXTURE into VIDEO RAM TWICE. I don't think they would specify it as 2X1G if the gpu's can access the others memeory space. With two cards we know for sure that one gpu cannot accress the other gpu's memory space. If you have to load the same texture to video ram twice you are mitigating any potential benifits of two gpus.

If the gpus CAN access the total memory space then one will be waiting while the other is useing the texture if they both need the same one.

And "distribution" of 3 on one vs 2 on the other means that one gpu is working 1.5X the other meaning that one gpu is doing nothing 1/3 of the time.



The 6970 according to that artical is 370

The 5970 is 589

No doubt prices are outdated but should still be relitivly equal. You will not get 589/370 more performace from the duel GPU under any set of conditions. Note that the single gpu has higher speed also.

Look at the performance per dollar graph .... The single GPU is 100, the duel GPU is 69. Higher is better ....




Just buy the cheapest 2G video card you can .... then spend the money you saved on system ram.

If we both have X dollars to spend and you buy a duel gpu and spend the rest on system ram and I buy a single gpu and spend the rest on system ram (and have more system ram then you do), my system will run 5-10 boxes of wow for sure better then yours. There is NO QUESTION about that. If you give any other advise you are 100percent wrong.

My junk systems are fine for 7 boxing on one computer cause I play in full screen and only stress my gpu as if I was playing one box ....


Lets say we ahve 800 to spend you spend 589 on the duel gpu and get 21G of system ram. Figure $10/1G for system ram.

I spend 370 on single gpu and get 43G of system ram.

My system will blow yours out of the water, assuming all the rest of both systems are equall.
