Second, ATI Stream Technology gives your system a significant boost by offloading tasks usually sent to your CPU to your GPU.

Is this just hot air or will it really compensate those of us who don't have the latest high end quad core or i7 cpu's?

Stream is ATi's version of CUDA. Specific applications include folding, compression and physics. So it's not a replacement for a cpu by any means.

3dmark06 stock settings - 5870 and i7 965 both at stock

22383 3DMarks
SM 2.0 Score 8704
SM 3.0 Score 10655
CPU Score 6282

ran it again without 16AF forced in CCC and got 22549 3DMarks, slightly higher
DMC 4 maxed at 1920x1080 8xaa16xaf with the 5870 and my stock clocked i7 965 and got the following
scene 1 162.78
scene 2 123.86
scene 3 221.67
scene 4 118.59

imageshack hardly counts as hotlinking tho as such :S the whole idea of it is for directly SHARING images... not like its stealing bandwidth off someones personal hosting where its part of a whole page.
 
Exceptionally dusty fan on that so called pic - also the benches he has posted seem low to me

Probably an early sample that's been doing the rounds, he says its on beta drivers and he doesn't appear to be all that clued up. And leaving a 965 at stock, sacrilege.

seems on par with the 4870x2 ....and then some

4870x2 scores at 1080p with 4xAA:
scene 1 - 144.58
scene 2 - 108.19
scene 3 - 175.35
scene 4 - 106.94

your 5870 scores at 1080p with 8xAA:
scene 1 162.78
scene 2 123.86
scene 3 221.67
scene 4 118.59
 
Hmm - I'd have to add 1920x1080 as a custom mode to test directly - but with only 3gig on the CPU and stock on the GPUs, max settings, 2048x res, x16 AF, x16 AA my 260GTX SLI gets:

scene 1 148.18
scene 2 120.71
scene 3 173.91
scene 4 106.15

Which stacks up pretty well imo... now to see what I can get at 1080p with some overclocking.

Without getting too anal, and taking this thread off topic, that statement is so, so wrong.

How is it going to create the venturi effect? A centrifulgal fan has poor efficiency by its very nature. Only a positive displacement fan would create the effect you talk of. Even then, a nozzle/diffuser assembly would be required to reach good performance.

Using a centrifugal fan, larger vents would allow more air to escape faster, simple as.


p.s. Nothing personal Kyle :)
 

Thats why I just managed...

scene 1 208.56
scene 2 146.14
scene 3 259.50
scene 4 122.83

With a Q6600 at only 3gig and 2x 260GTX SLI with only v. mild OC (576->590). using 1080p, maxed settings, x8 AA, x16 AF.... might be some degree of CPU limitation but not that much.


EDIT: BTW they are clearly GPU limited in that link not CPU limited - they are topping out the GPU once the core 2 quads hit ~3gig and not seeing any faster performance for an extra 600MHz on the core.
