Ok I am seeing people that have hit 800mhz on the core without much trouble on this exact same 9800GTX. That will actually be a very nice bump over my 8800GT which maxes at 712 on the core.

I bet the shaders and mem go a lot higher too.

I like the idea of being able to see the percentage difference/advantage for each card compared to the others when you mouse over them in this computerbase review (http://www.computerbase.de/artikel/hardware/grafikkarten/2008/test_nvidia_geforce_gtx_280_sli/17/#abschnitt_gothic_3) .. pretty neat feature IMO! :thumbsup:

This one chart is enough to totally put me off. Unless they sort this with a driver these cards would be no good for me as I play FSX quite a bit. :(

Good to know. So you're finding the card good with FSX?

Obviously driver issue ..

Yeah. GPU is not really important anyway. FSX is heavily CPU limited.
But there's definitely no performance downgrade compared to other cards.

With the 280 and it's newer drivers you aren't seeing stuttering are you? I can't use any driver version above the 169.xxs with my 8800GTX without horrible FPS swings and bad stutters in FSX.

What is it that makes a flight sim so CPU limited? I've never really understood that.

How can hundreds of AI soldiers in an RTS or dozens of bots in a first person shooter (with realistic physics) run at 80+ fps when Flight Simulators seem to be stuck in the 20s indefinitely?

How can they be THAT CPU heavy with a single object moving through the air?

If they are actually simulating the movement of air over the wings, I can see how that'd bring a decent CPU load... but looking back at the numbers, it still seems like a bit of a stretch to think that the fastest cpu on the market can barely manage 30fps average.

All these reviews are totally useless. No bench in 1280*1024 and 1600*1200.

FSX attempts to simulate real flight dynamics. So, yes, there's a lot of calculation going into wind speeds, resistence, air pressure, and other physical factors affecting flight. It's also calculating those things for any other AI planes you might have flying around. That's why you get such a big performance gain by turning off AI controlled aircraft.

Still nobody knows where these came from. I'm not saying they're outright fakes, but I sure would like a source on these. If we take tweaktown's 4850 review and the Crysis DX10 Very High benchmark numbers we can calculate how much better the 4870 must be to meet and beat the 280.

The 280, in that review, is getting 21.7fps in Crysis, VH, DX10, 1920x1200. For the 4870 to match exactly the performance of the 280 it will need to perform 52% better than the 4850. For it to outperform the 280 and get, say 25fps, it would need to perform 75% better than the 4850.

Unfortunately, there are no 4850 numbers on the above supposed AMD benchmarks so we can't calculate a percent gain for the 4870 since we don't know if these numbers we aquired using the same benchmark conditions. However, given all that, these numbers actually look pretty realistic, and pretty good. If they true out to be pretty accurate I certainly hope they drive prices down because I still would prefer having a 280 since it still appears to yield the highest single GPU performance you can get.

At last, a GTX260 SLI Review

80-90% increase from the second card :)

Looks like PhysX is going to have a larger impact in the near future-

"We also spoke with Brian Burke (Senior PR Manager) and Roy Taylor (Vice President of Developer Relations) on the phone and they had a ton of things to say about PhysX and were obviously all for it. They were happy to announce that 14 to 16 new PhysX game titles would be available before Christmas and double that next summer."

GT200 Physx beats QX9650

Left - CPU Physics Processing, Right - GPU PhysX Processing
Source: 3DMark Vantage

Test Notes: 3DMark Vantage tested in "Performance" preset mode, with and
without GPU PhysX enabled, on Core 2 Extreme QX6850 powered test system
running Windows Vista Ultimate with the Forceware v177.39 graphics drivers
and v8.06.12 PhysX drivers on a pair of GeForce 9800 GTX+ cards running in
SLI mode. With GPU PhysX disabled, the overall 3DMark Vantage score is
P11720 with a CPU Test 2 score of 14.95 FPS. With GPU PhysX enabled, the
overall score jumps to P14298 with a CPU Test 2 score of 127.77 FPS

amazing this physx support, and the influence in futuremark tests
intel QX9650 is completely beaten by GT200 with physx enabled!

For the price of a 280 you could almost get two 260's :D. They're awesome in SLI!

I play 1920x and was looking @ this-

http://www.tweaktown.com/reviews/1481/6/page_6_benchmarks_pt_boats_knights_of_the_sea/index.html

That's a GTX 260 @ 640|2300 keeping pace with an overclocked GTX 280.

I can still refund mine and may very well do so to get a 260 to OC.

But you need a nV board... :(
& you are going to suffer the SLI issues.

a single GTX280 for me please!

Been using SLI for 18 months now and had very few issues. The early Vista days were a bit poo because of the drivers, but I currently have no issues at all with SLI. As for the mobo, it's faultless. I admit the 680i chipset was pretty pap (I got it swapped for this one for free) but the only issue I've had with the 780i is the video corruption issue, which is now sorted.

SLI is the only way to play Crysis on VH at the res I use ;). Also with these new cards there has been no micro-stutter at all :).
