no, your missing my point, the usage percentage is really a measure of how much of the devices bandwidth is saturated. a game will rarely keep 100% usage.

Now I am just confused. What is a bottleneck and how do I test for one.

just trust me, theres no bottleneck in that system. if you really want to look for one, look for 100% CPU usage combined with ~40% GPU usage in a highly GPU intensive game such as metro 2033 or the like.

So if I moved to a GTX580 I might actually bottle neck the card since it is fine with the GTX260s in SLI? There is no better CPU for gaming really to buy and I can't SLI 2 2500ks LOL.

There´s your answer. The Witcher 2 is very gpu intensive, which means that there´s no bottleneck in this particular game. Try something like Oblivion or BFBC2. I guarantee that your system will will want more processing power in BC2 @ max. My Q6600 @ 3.2Ghz was a bit of a bottleneck and I only have a 5870.

I don't understand what your saying a 2500k will perform optimally with ANY GPU in the current market. if 2 260's are being "bottlenecked" its more probably due to poor scaling in an older generation of SLI

your not serious, right? BC2 is the worst example ever... it has CPU emulated everything it doesnt even have hardware level sound processing

Why would he want to test for a GPU bottleneck in a game that is mostly GPU intensive? That does not make any sense. I can assure you that he´ll see a bottleneck in BC2 with a Phenom I @ 2.5ghz on a 6970. Change that CPU with a 2500k and his average fps will more than double. His card will not be fully utilized with his current CPU.

I think the "GPU" usage is BS..

Just check the FPS..

I ran Dirt 3 Bench with my 9950BE 2.6 Ghz with my 5870 = 27-31 FPS
i5 2500k@ 4 Ghz = 58+ FPS


Bottleneck DEPENDS on the app/game running.

^who use hardware sound processing these days?
realtek is taking over the sound business, guys.

either way, for the best advice on bottlenecking you should consult brettjv. he's the master of bottlenecks

and no, while gaming your GPU is suppose to be as close to 99% as possible. my GPUs are 95-99%, mostly 98-99% when I play crysis, crysis 2, or run the unigine heaven benchmark.
my cpu rarely get use over 50% unless it's cpu intensive games such as FSX only THEN i see like 90% max. your cpu graph does not have to be completely maxed out. sometime just one graph or one core maxed out and you already have a bottleneck. most games are not quad-core ready yet.

this advice is taken from brettjv
try making your task manager show only one graph for the cpu (not 4 for each core, but total cpu usage). go to view, cpu history, select one graph, all cpus.
if the % is constantly pegging at 25%, 50%, 75%, or 100%, you know you have a bottleneck.
25% > single core bottleneck
50% > dual core bottleneck
and so on.

btw next time post in the cpu section.
