impressive figures for the xfire 5770s... considering the total cost of both cards, i can see why going down this route is so tempting! hmmm...

1Ghz 5770's come very close to a stock 5970

I think I'll stick with the single 5870 really. It's cheaper to run, quiter (I guess?) and like others say probably better for minimum fps.
By pennies and the minimum fps thing is driver issues not the card.

Great cards just don't expect them to scale great in all games, the 5870 will scale great in all games, if your on a budget and want decent performance go xfire 5770's. No budget and you want sublime gaming, enthusiast style, get a 5870. I did and the impact it has had on my gaming is unbelievable.

Or maybe he should just get the best for his money, the 5770 Xfire?
I wouldn't say the gaming experience with a 5870 is any more sublime than a 5770 setup. I've had both.
Have you ever tried a modern crossfire setup from ATi?

From my own personal experience the crossfire 5770's are extremely good value for money and I am impressed by their crossfire performance.
However, While they exceed in many games in max framerate over a 5870 I found even with the max framerate of the 5870 being less than the crossfire 5770's I found it was smoother on the 5870.
That's in no way to discredit Tom's post but just a different experience to his.
I also feel that driver maturity is the key here. As there are a few games which don't exactly play ball with crossfire 5770 but still run.
MW2 and the thermal scope is one issue I am hoping they will sort out as well as demigod. Demigod is the main one for me as I like to play that a lot . A few games don't seem to be as smooth as when I had the 5870 but with the next few releases of the drivers I am sure it will improve.
Also Ben post left me a little perplexed. Limited by crossfire? I am not sure what he meant by that but crossfire is only as good as the cards and motherboard you use it with. The crossfire 4890 setup I use to have had very high framerates and was smooth as far as I could tell. It was faster than my 5870 and faster than the 5770's.
Never noticed microstuttering on the sli setup I use to have or the crossfire 4890's but have noticed it in demigod using the 5770's or what at least I think is microstuttering. But I am no expert on noticing these things.
Also I wonder if he has any real experience of these cards rather than going on what other people say or what reviews say. The webbo's, fornowagain(sp?), reflux's test stuff for themselves. Ben seems the type who just listen to others who hypothesise and then go round making posts about that.
I think the issue here with the 5770's not being as smooth for me as the 5870 even though it faster in most of the games I have played is due to either limited memory interface of the 5770's or it a driver issue.
While it remains a fantastic way of having 5870 performance for less money, overall the 5870 worked better in my setup but other people mileage may vary.

I started with the 5970 and frankly was not happy with the price to performance ratio of it compared to my current 2x280GTX's.
Although I still want to setup eyefinity!
It came down to my experiences with both SLI and Crossfire which were hit and miss so I eventually came to the conclusion that the best card price/performance multicard efficiency etc was the 5870 so I bought one.
For all the 5770 owners out there please remember the 5870 also clocks very well.

Do people find smoothness issues of multi gpu set-ups worse or better on two cards or one X2 gpu card? So for example, two 4870's or a 4870X2 / 260gtx sli or a 295gtx. Keeps bugging me this, would like to hear peoples' experiences / opinions.
I think most people will say that smoothness isn't an issue, every now and then someone will say they think they get problems in multi GPU to fuel the fire, but I don't think it effects many people....if it did, Sli and Xfire would not be rated at all as viable tech. Besides, aren't multi GPU cards essentially either sli or xfired GPUs on one card ? someone correct me if I'm wrong.
Its a bit of a lottery really, although quite a lot of games support Multiple GPU's the different software implementations effect the way the performance scales, some games scale well some do not.
For instance if you have a Crossfire or SLI system you may be in a situation where only one card is working so the speed of the game / application will be directly effected.
Single GPU systems will always run at the same speed.

I appreciate the 5770 Xfire may not suit everybody and as you state the 5870 can clock well, but its made me and others happy.
The "happy" fact for me was I only paid £224 for 2 x 5770's that can run at or near 5870 performance and surpass it occasionally AND I saved myself approx £100+over the cost of a 5870 (gave that to the wife to sweeten her!)

Yes MultiGPU cards depend on sli and crossfire so suffer the same drawbacks

That's exactly it, the 5870 just is not worth another 100 quid. It makes no sense if you have an Xfire board P55 or X58/48/38 only worth it.
With current prices I would have to agree, HD5870's are still overpriced due to supply, wasnt the case during launch though.
Surely if you didn't want the hassle of crossfiring 5770s or the added cost of a 5870 you could buy a 5850? They clock very well too, too the point of equaling a 5870, costs the same as two 5770s, and can be upgraded with another 5850 at a later date. This is the main attraction of a 5850 for me. Unlike the 4 series where the 4850 had GDDR3 and a much slower core, the 5850 isn't much slower than a 5870
