SLI CrossfireX a waste of money?

post #1 of 26
Thread Starter 
I was wondering if it was ever cost beneficial to SLI/CrossFire. It seems like a waste of money for me because you will only get around a 50% average FPS increase (correct me if I'm wrong) depending on the game. I think it probably would be much better to just sell your old card and buy a better one vs. buying the same card you have to SLI/Xfire.

Since, it can almost be assured that there will always be a single-card solution that will run the latest games on the highest settings, SLI/Xfire is a waste of money. I think the only people who really should SLI/Xfire are hardcore gamers who want more graphics than any single video card can provide.

Am I right?

It isn't useless for some people because they have the money to spend. Xfire/SLI requires a lot of power, so a higher PSU plus a nice Mobo (preferably 8+2 Phase Power). On top of that, a nice, stable OC is required to keep the Xfire from Bottlenecking.

I prefer single GPU configs but SLI/Xfire isn't useless. Especially if you could find another older GPU for cheap on ebay rather than spending $500 on a 680/7970.

It's all preference IMO.

Edit: In your case, it would be great. 6850 isn't too power useful and could be quite powerful if Xfired.

most of the time people will run games decently with one gpu sli can give you higher framerates for some people that are

using multiple monitor or high res , 120hz monitor and for my two 580GTX i would say i have 75% framerate increased but there

are some bads too sli and CF driver issues stuttering heat so i think thats good if you have some extra money and want no

framerate drop below 60fps

What your leaving out is these newer cards Scale like crazy.

Even my soon to be replaced 5770's get close to 100% at times.

Then take into consideration you can run one top card out and then double up at
a lot cheaper price than new and be right back on top again.

My take on it.

Later:D

Sort of. lets look at price first. Sometimes people are able to get a good card at the moment and then add a second later on, which is usually more expensive than buying the top end single card. So if the cards you want to SLI/Crossfire are 350 each and the high end card is 600, yes its costly but sometimes easier to get one card first and then another down the line.Some people may not be able to save up the 600 all at once. And depending on the cards used two lower cards can easily match/outperform the single high end card. Recently I picked up two 480's for $100 less than a single 680. In some cases the 680 wins, in some mine win. So since I get basically the same performance for $100 less it's a win for me.

Second, some games scale really well with two gpus. Take a look at battlefield 3. More and more games will be supporting mutliple gpus setups I believe. SLI used to be around awhile back, then it went away for awhile and now it's back.

SLI/Crossfire opens up another upgrade path. At the time I bought my second 470 I got it for around the same price or less than I would have if I sold my other card and replaced it with a 480. Not to mention it performed better than a single 480 would have.

Considering that there is still terrible support for Xfire/SLI.....

The performance improvement from SLI/CFX varies a lot depending upon the game engine. Some games see close to 90 to 100 percent improvement one one end. Other times you get 5 percent improvement or even worse performance than one GPU. There are other games that perform somewhere in between.

If you have the money to buy two GPUs, it is better to get one stronger GPU for less concerns about performance or bugs.

SLI/CFX makes more sense at the ultra high end vs. as a budget purchase.

If you can do it without uprgrading anything else, and get your second card cheap/used then go for it. Thats mostly how I did mine. Otherwise its best to stick with a single card upgrade. Unless of course you want tri sli gtx 580's or something nuts.

I have no OC and I get no bottleneck on my GPU usage. Most newer CPUs shouldn't bottleneck on multi-gpu setups
