The GPU is the current bottleneck and most highly used resolutions and probably ALL resolutions that people buying a 8800 or R600 GPU are using.

At 14x/16x everything else on max/highest settings in HL2 @ 16x12 resolution a pair of R580's could only pull an average 33FPS in the Lost Coast demo (at 2D clocks 500/600 because I didn't have time to fiddle with cards that have two very different OC characteristics to run at a respectable frequency at the sametime... they still pulled 9200+ in '06). Try to tell me that the GFX isn't the bottleneck in that situation.

The current GPUs like the 8800 GTXs are not the bottleneck unless you want to play Oblivion or Microsoft Flight Simulator X at 2560x1600 at 16QAA and 16AA with a single 8800 GTX.

The current problems we have are the major bottlenecks that are caused by the CPU. Even the QX6700 is still bottlenecked by SLI 8800 GTX and DX10 is there to try to get the GPU do all the graphical work, while the CPU does all the physics and AI. And when this occurs, the GPU will not be bottlenecked unless you try to play a game that is way beyond the specs of your PC.

Example being me trying to play Oblivion at maxed out settings with an X1600 Pro.

And I'm not sure where you got the 33FPS in Lost Coast with a pair of X1900XTXs because that is extremely low.

Apparently you know everything, so, go right along and believe that the CPU is the bottleneck.

You sure are smart. The GPU surely is the bottleneck.

Nevermind that rather irrelevant test that you just pulled up on 12x10 res with no AA or ANISO....

Quote:
"A bottleneck is where a component, or multiple components, within a computer system are incapable of processing data at the speed of the higher end components within the computer system. They therefore prevent the system from operating at the speed which the faster components are capable of."
A definition from The_Manual.

Well if the bottleneck of SLI 8800 GTX disappears on a X6800 at a processor speed of +4.00, then SLI 8800 GTX would not bottleneck the processor until maybe about +5.00.

Another point is that not everyone can afford a brand new processor, a huge resolution monitor, and get a high tier GPU at the same time. Like I said when DX10 gets rid of the bottleneck problem, that would allow many people with Non-Conroe processors or monitors with low resolutions to be able to buy a 8800 GTX or R600 worrying about being forced to buy other hardware to fully utilize their GPU.

Thats SLI GTXs... not one. With one GTX it's significantly lower... like 3.0Ghz... and that's not even on 16x AA yet. Arguing money is moot point since they're already dropping $500-650 on ONE GFX card... to plead the case of spending a couple hundred more on a different processor is a sad fall back.

As for having to buy a new monitor... WHY BUY A CARD LIKE AN R600 OR G80 FOR A LOW RESOLUTION MONITOR WHEN THERE IS NO POINT? To get 400 FPS more than your monitor can output? Who cares if the CPU is the bottleneck at that point? Come on... you can do better than that.

As for having to buy a new CPU, that's still a pretty weak position as mentioned above.

... all of a sudden your argument has totally shifted direction. At first it was "CPU is the bottleneck". Now it's "CPU is the bottleneck at low resolutions and low settings and it's too expensive to upgrade the CPU and it's too expensive to upgrade monitor and ...and...and..." Stop stalling and argue your original point... or abandon it.

Both you and I know that what you're trying to argue is irrelevant at best. The cards are made and marketed for the ultimate cutting edge buyers that are using super high resolution monitors and/or benchmarkers... not the budget-minded 'I-can't-even-afford-a 16x12 res-monitor-and-just-want-to-play-CS:S" crowd. At that level, the GPU is the bottleneck. (Perhaps that not in the benchmarking realm where they futz around with low 12x10 benching and everyday useless LN2 runs. but that's even FURTHER from begin relevant.)

A 1920x1200 monitor costs at least +$650. For those who have smaller resolutions, and non-Conroe processors, they will still have bottlenecks even if it is small. DX10 will get rid of those bottlenecks.

One of my friends really wanted an 8800 GTX for his birthday to max out games like Crysis and Unreal Tournament 2007, but he was worried about the bottlenecks that would occur because of his AMD X2 3800 and 17 inch monitor. Now he feels a bit better knowing that the bottlenecks will disappear because of DX10.

Well the bottleneck will not completely disappear, but it would certainly be much better than without DX10.
