SLI vs Non-SLI

post #1 of 16
Thread Starter 
This question is related to SLI and CrossFire..

Price per performance wise, is SLI more costly then just buying a single GPU equivalent? I seem to get that feeling, but maybe I am missing the reviews on the good multi-GPU setups?

What are your thoughts?

nope,heres an example,2 460's is $400 a single 580 is $500 but why spend $500 on it if 2 460's outperform it and is $100 cheaper

lol, if that were the case, very few would go sli. You have it backwards. SLI/Xfire is almost always better in terms of price/performance.

And you feel like a straight bad-as* with more than one gpu.

If money is an issue to be honest with the rate of driver progression and SLi improvements it makes a lot more sense to get 2 lower cards that cost less than 1 top card. They will outperform it and do it well. Seriously can anyone think of any game where sli doesn't work these days?

It depends on the card. TehStranger? has a good point with a High-end card compared to a new High-end GPU. You pair two slightly older High-end GPU's together vs. a New High-end GPU, and the older ones kick the new one in the face. It's like a 6'5" guy vs. a 5'8" guy in a fight - who do you think would win?

Well, you would most likely think the 6'5" would win. But, the 5'8" guy knows more 'moves' and kicked his butt.


you get my drift?

It is not a better price/performance.

SLI is a technology to give us a temporary solution until a single card is enough, I would say we have reached this point at 1920x1080, but for eyefinity or 2560x* SLI or CFX is a viable solution.

It's very possible to get better price/performance with a sli/crossfire setup as shown in the fine example above. One thing to consider is future upgradability. Once you have 2x460's (I actually bought 2x460 se for $100 each recently for my last build) you pretty much have to scrap them to upgrade.

On the other hand, if you have a 580, you could always get another one later (if your board supports SLI).

I have to admit I am a sucker for dual-gpu systems. It just looks bad@ss

Another thing to consider is that sli/crossfire can sometimes be flakey, sometimes actually getting worse performance than just one of the cards, and we cannot forget microstudder.

My advice would to get the best single card solution you can afford so you dont have to deal with the headaches.

I say spend the extra hundo and get the 580 so that next yr you can buy another 580 to kill the new 710 for an example. But if u already have a 560 or so go sli with that card

Yeah, this is along the lines of what I was thinking too...

In order for me to go SLI I would have to also buy an SLI board, get a faster CPU, and an 850W PSU. I would still need to get a Sandy Bridge CPU in order to take advantage of a GTX580, however I could cut costs on a non-SLI board and keep my 650W PSU... So in my case, maybe keeping my PSU would equal a higher price/performance ration then being forced to buy a new one just for SLI.

Also, when it comes time to upgrade I will only need to take a loss on one GPU rather than 2...

Question about the GTX590--- since this is actually 2 GPU's in one card, does it also have any micro stutter problems that SLI/CrossFire setups do? Or is it a very fast and reliable card?
