This is one of the few times I'll actually have to argue against TPU!
This was a launch day review, and there were clearly issues (either with the driver or their test setup) that caused some significant outliers in their benchmarks.
Check out the results from Call of Juarez.
SLI 560 Tis barely perform better than a single 560 Ti at 1050p.
The same can be seen in the Riddick bench
, where the SLI 560s run equal to a single 560 at 1024x768.
AND most notably Farcry
, where SLI 560s score the lowest in every test from 1050p up!
I love citing TPU charts as much as the next guy but this is one of the few times their results were skewed by quite a bit. The "10%" overall performance stat, should really be between 20-40%:
(the 560s in this one are very slightly
OC'd @ 880/1750/2100)
Just wanted to clear that up!
As for the OP's poll, I'm of a different mindset than most it seems. I tend to look for good price/performance from my card(s), and prefer to buy the power I need up front. IE, if I'm going to run SLI (which I have for my last 3 builds) I get it all at once, instead of buying one card and waiting months/years to add a second.
People talk about upgrade paths available from having a single 580, but I don't see it as being much different than upgrading from a multi card setup. Sure, someone with one 580 can just buy a 2nd one and toss it in. But someone with SLI'd 560s can just as easily sell them off and put that money towards their next purchase. I don't see the distinction.
All that said, Arizonian, since you already have a 580, I'd really just keep it. Like you said, you'd probably have to sell it at a loss, and while you would get a significant performance boost, you really don't want to bother running multi cards if you don't have at least 1 space between them. The heat will absolutely kill temps on your top card, even with the cooler running 560s.
If Nvidia keeps their promise, Kepler is only 6 months away. Edited by Booty Warrior - 6/21/11 at 1:47am
