Why do people go SLI/CF with new rigs? - Page 3

post #21 of 65
2 cards can be faster than 1, and cost less or the same for more performance.

It is fairly simple.

I just recently upgraded from dual AMD 5770's to an AMD 6950/70 and I have discovered that a lot of the "problems" that I thought were being caused by Xcrossfire are still present with the single GPU. Just FYI, I do see a bit of an improvement in the smoothness of the gameplay but I now think that is more to do with the 256 bit memory interface than the Xcrossfire itself.

In my case, a single 6950 with unlocked shaders and overclock outperformes the dual 5770's in the same system and the same games/benchmarks.

So now I am saving for another 6950/70. ;-)

Thier loss.

In many cases two midrange GPU's have scorched high end GPU's for less money.
I'm telling you both from experience that I can see a difference. Granted some games honestly gain from sli/cross fire. But for me that's only half of my games, if that... Not worth it imo...

Well, in my case and other people with high res monitors, high end cards tend to have more VRAM, which is needed if you're running eyefinity or a 2560x1600 setup. I usually would buy 1 single high end card, then run Crossfire/SLI in the future.

But that's all different for the commoners with 1920x1080 setups.

From experience I can tell you that a single GPU option IS always better than two cards in SLI/Xfire.

The price/performance difference is always minimal and sometimes it can even cost more to get two cards over the one more powerful one. Using two video cards in Xfire is also not supported in all games and even when it is supported it generally does not give you as much performance as the single card would. This on top of the fact that two cards generate much more heat and consume way more power than the one powerful one.

Bottom line is having two and three graphics cards in your computer is a gimmic to make people buy more cards and something to give people bigger e-penises.

I had two 4850's in my rig but all it did was cause me problems, I will never make the mistake of jumping on the Xfire/SLI bandwagon again.

Also this. I got better performance from a single 4850 then I did with two in Xfire because of all the glitches Xfire was causing.

Look at is like this.
1) 2 x GTX560 are a lot faster then GTX580 but = in price
2) If you get a GTX580 not thinking its the faster single card and hope in mid that latter you can SLI for more performance then would that be the same since by the time you get a 2nd one Nvidia will have a better single card solution.
3) From what i see people go with second or third card right away or within 3 months, after that they dont bother.

You would quite simply have to be mental (or loaded) to buy a gtx 580 when you can buy 2 gtx 460s for much less and get better performance. Thats my take and why I bought 2 gpus with the intention of running them together, for the performance I want

GTX580 is faster. Even if GTX460 might get 3-4 more fps in average GTX580 will get more consistent fps.

I bought one HD5870 about a year ago and just bought another because the price was coming down because of the new HD6900 series that came out. but at first was was going to do two 5770's because it was close in price and better but then thought i can do what i did and kind of what the OP was saying that you can buy one highend card and then another later down the road and have more performance then the two lower end cards beating out one faster highend card, and having to throw out the two lowerend cards to rebuy two more lowerend cards that beat out the new highend cards that come out
