I was reading an article about the 5970, (don't confuse it with the 5870 which is what most people have, and what came out first and is still a very good card that beat the GTX 285) and I was trying very hard but I could not keep my jaw from dropping. This just from two sources but the results are amazing, and the overclockability with increased performance from overclocking is more than stunning. I recommend you read the guru3D article first.Link: http://www.techspot.com/review/221-ati-rad...5970/page4.htmlhttp://www.guru3d.com/article/radeon-hd-5970-review-test/14To people that want to bash you should probably read one of my previous posts first:http://forums1.avsim.net/index.php?s=&...t&p=1723507EDIT: Sorry about that guys, didn't notice I made the title 5890. Its supposed to be 5970.

The 5970 does nothing for MSFS beyond what a 5850/5870 will do, due to it's dual-GPU architecture.

I never said anything about FS... but ok, whatever you say. I think anybody would say its nothing short of amazing though. I bet this card even make the Pentium 4 look amazing! ...and I know someone will say that Phenom CPUs will be a major bottleneck to the card. First the i7 and the top Phenom X4 bandwidth isn't significantly different, and they probably developed these cards on Phenom CPUs, since it is AMD.For people that want to bash the price to, here is a quote from an Anonymous person on Tomshardware (Page 2 of comments)Source: http://www.tomshardware.com/reviews/radeon...0,2474-15.html#

Why do all these reviews bash the $599 price tag? When the 8800 GTX debut, it was higher. Then 295 had a MUCH higer price tag. What you are getting with the 5970 is essentially 2x 5870 if your PSU can handle it, as ATI built these things to run at 5870 speeds. So don't scoff at the price, being that 2x 5870 is $800. Similarly, the 295 is $500. It beats the 5870 in some games and gets beaten by it in others, yet its $100 more. The way the 5970 kills the 295, being $100 more is dirt cheap.Secondly, enthusiast or anyone who opts for CF/SLI options, at $599, this card is pure win as that's similar to 2x 5850 which cannot be OC much, and $200 less than 2x 5870, which given how well this card OC to 5870 speeds, its a no brainer. There's no point in getting 2x 5870 imo now if your PSU can handle the load over 2 rails.

You're posting on an MSFS forum and your thought process had no regard for MSFS - why even post? Sure the 5970 is a fast card, but it sits in between a 5850 and a 5870 in terms of MSFS performance, and you'd need to disable Crossfire in order to ensure application compatibility. Doesn't sound like a very good card for MSFS, now does it?

This is not a MSFS forum, the forum was made with flight simulation in mind, and that includes all flight simulators. You don't need to disable crossfire, because the card uses 2 GPUs, not dual boards, its two GPUs on the same PCB with an interconnect interface, its a different than SLi and Crossfire. Maybe you should study up on it. I don't see why you say "why even post", do you really love bashing companies that much?I'm posting from a technology perspective, not a MS FS9 or FSX perspective.

ATi's multiple GPU solution IS CROSSFIRE, regardless of the physical configuration. I suggest *you* do you some studying.

I bought one of these for my Th2Go setup and it's been pretty good.I specifically bought this card as I saw a Tom's Hardware article that demonstrated more fps using in at high resolutions than the 5870I had to decrease the level of antialiasing(which kill framerates in this thing), but otherwise been a winner.It gets better with every driver update.Right now I am getting 30 - 40 fps in Tongass Fjords Sitka with the Beechcraft duke which is amazing compared to what I was getting with the gtx 285 and Th2Go.It is remarkable overclockable, I am over clocked it by like 25% with no problems whatsoever.

Absolutely correct!!!Read about it here and become informed.Yes the 5970 is blazing fast, but so was the geforce 6800 Ultra when it came out years ago.

A question for you, are you running the card with Catalyst A.I. disabled?With no FSX profile in the Catalyst drivers, there is no way to force Alternate or Split Frame rendering on the game which renders the added GPU useless. Keep in mind that the 5970

No it's enabled for FSX, I tested with and without and got better performance with the Catalyst AI enabled.

(Near) total n00b on this, but why is there no FSX profile in Catalyst?What could be so hard about implementing split-frame or alternate frame rendering when 2 GPUs are available, each with their own 1 GBy VRAM?The benefit would be a huge increase in frame rates for multimonitor setups with lots of AA and clouds where the GPU can be the bottleneck.I have never found an answer to this and I do have a 4870X2 that I would love to get my money's worth on. And if alternate or split frame rendering were to work on a 4870X2, then it also would on a 5970, and that would just be sweet...Cheers,- jahman.

The question is are you getting a performance increase from actually using the two GPU's or from image quality optimizations that are enabled when using the "Advanced" Catalyst A.I. setting?How about the "Standard" setting, have you tried that?

I have actually, I did a day of testing before I picked my final settings and the framerates were definitely higher with Catalyst AI on, I have another profile where it is turned off because some of the other programs won't run with it at all.
