Does SLI really improve your graphics?

Question

I have a 7600GS PCIE and Im going to buy another one to put it in SLI, but I don't have enough money to buy the 7900GT Ive always wanted. I wanted to know should I go for it or should I save up for the single card 7900GT? What also made me ask this question was that two cards in SLI doesn't improve performance at all, it's just the same thing.

I ment as in will a game run better on one 7900GT or two 7600GSs.

Answer 1

Those last two answers are ridiculously wrong. Two cards set up in SLI will split the work between themselves automatically, hence the game does not have to be "designed" to use it. That being said, the improvement you get from running SLI is not that great, and two 7600GSs in SLI will not be as good as a single 7900GT, so I would recommend you continue to save up.

Answer 2

Many people say that SLI makes you have mor epower through your video, however no game is capable of running SLI so SLI is just another reason for NVIDIA to make more money by not telling you that its better to buy 1 good vard (Nvidia 7950GT Nvidia 8800GTX). This is the same thing with Cross Fire, both are really a scam at this point in the industry.


A game will run better on one 7900GT at this point.

Answer 3

I wouldnt worry about SLI. I know people that run sli in BF2 and its accually slower than if they run one card. so yes the game has to be programed to run sli. I would get the 7950 GT OC 512. what I have and its awsome.

Answer 4

The game has to be programmed to work with multiple video cards. I don't know of any games that are, since most machines only have 1 card, why would the developers waste time targeting more than 1 card? If you were a developer you might test with multiple cards for compatability, but I can't see any other reason for running two cards, except maybe if you want multiple monitors.
