New ati radeon hd 5830 getting lower fps than gtx 260 HELP!!!!!

Update the graphics card drivers and report back to us.

also, specify the PSU manufacturer please, and the model number or name.

What resolution are you gaming at? If your gaming resolution is high, i think the extra memory is coming into the picture and since the GTX260 is the superclocked edition you are getting better min frame rates. Ideally the HD5830 is somewhat around the HD4890 mark. So it should be more capable than a normal GTX260.

Also, which drivers are you on the Catalyst?

catalyst 10.3 the latest ones really lowered my frame rate even more.gaming at 1920 1080

Catalyst 10.8 are the newest drivers!!!
Also, you nave an i7 in the other rig, which pulls out a little better fps in most of the games.

what i meant was that catalyst 10.3 gave me the best fps out of the other latest ones i tried

Oh, now i see that the GTX260 is a superclocked version. There's your answer. Plus that, as i said, the i7 tends to pull out little better fps in games than the PII X6. The HD 5830 = HD 4890, stock GTX260 = HD 4870.

Gaming at higher resolutions makes the 1792 MB of memory really come alive. Plus the superclocked edition really churns out more than the HD4890. So, you have the answer.

But try once with the 10.8 and see if there's any improvements.

The superclocked 260 is a stronger card. The OC makes the card routhly equal to a 4890, and the extra RAM pulls it ahead.

When you put more into your picture your frame rates will drop....your 260 has what... 216 stream processors, so try this... turn down the quality settings on your 5830 and your frame rates will go up. The old agp had a software texture swap called a gart that helped a lot with quality and speed... I'm only guessing here but doesn't the stream processors do a very similar function as a hardware solution? The 5830 has 1120 stream processors about 5 times what a 260 has... that's a lot of asset dedicated to quality so maybe if you just tone down the quality on the card you should raise the frame rates... I have my 5830 clocked at 850/1050 and I get around 20 to 25 fps on the low end and 40s to 50s on the high end with crysis. I put my game graphics settings on all medium and point my driver software at application settings. It just seems to me that if you have a need for speed and game play then get an Nvidia card.... if your into graphics quality get a Ati card and remember there is always plenty of adjustments that can put you near the middle.

ATi uses superscalar architechture, each shader is counted as a 5-way shader, and can do 5 operations in a cycle. If this isn't optimized (if this operation fails) then the GPU loses it's theorethic effectivenes. Nvidia's architechture is scalar and is 100% effective.

HD 4870= 800 shaders, 800/5 = 160 shaders.

whats the use of all the quality when you cant get the performance to balance it?

Did you mean quantity? 

no.i meant quality.according to benshami ati gets higher image quality with worse performance while nvidia gets balanced quality and performance

PLEASE show me where an i7 QUAD core pulls more fps than 1090T? talk out ur ass much Ha.

prob have triple channel LOL
