OK, I've had a XFX 6870 and three 560s. I'd say the 6870 is no 560. Beyond that, I can link to about every review on the net that says the same.

As far as "games being optimized for NVIDIA cards" I don't even see how that matters. If you play a game that runs faster on nV cards because it was optimized for them, the net effect is the game is still running faster.

The 6870 only won 1/14 games in that Xbit review I linked to and none of the synthetics. That's a pretty good indication that the 6870 is the slower card.

I'd agree the two are pretty close in multi GPU, but CF drivers aren't exactly building a good rep lately. I've seen people I thought would rather buy an Xbox than use NVIDIA cards buying SLi lately out of frustration with CF drivers.

You had "a" XFX 6870 and "three" 560. You're comparing the "three" 560 vs "a" 6870? Now, if you would compare 560 SLI vs 6870 in CF then your opinion would be more legitimate. A single 560 would beat a 6870 but I believe the 6xxx CF performs really great.

As for the crossfire driver issue... There are people who have problems and those who don't. I guarantee you some people have SLI issue as well so 90% of the people who have drivers issue are usually user error related.

The 560 is retail at $250 great card at a great price. The 6870 is also retail around $230-$250. If you can cough up an extra $15-20 for a 2GB 6950 then I say go for it. If you can only afford a 560 and 6870 then I suggest go for the 6870 "Black Edition". The "BE" is a really strong card with performance as close as a 6950. I've seen benchmark b/w all three cards and 6950>560>6870 but when we're talking about a 6870 black edition then it goes something like 6950>6870 BE>/=560.

Best of all the 6870 BE retail is $235 and AMR is $215 best bang for your buck period.

You'd know a lot about that. Clearly you're biased towards the green side, so why even offer your opinion? There is no real evidence to show that CF drivers are any worse than SLI and both have their problems. Having owned a Crossfire and SLI setup I can say that I had no major problems with either that would put me off from buying. There are a number of people who have issues with AMD drivers but those are still a small amount cases and if this was such a widespread issue, how can AMD products be selling with an issue like this?.. Its mainly down to user error and then fanboys make a big deal out of it. NVIDIA drivers have their problems too. The driver excuse is getting old.

The article I linked to states that the card was overclocked (not a huge amount) and It was able to keep up with the 560 on average. Nobody said at stock it was faster. In a multi-gpu setup they are neck and neck but the 6870s are a cheaper option.

I would go with one single card. I regret getting a second 5870 because some games get very strange when crossfire is on. I am considering selling both for a 5970.

One thing to bear in mind is that virtually all the 6950's can be easily bios flashed to 6970 specs.

There is a lot of talk of the new PCB and 1GB cards not flashing but I wanna grab a 1GB and see.

Presumably you mean a 6970 as a 5970 would be two 5870s in crossfire on a card.
