Woot! Just another reason as to why I am getting two 9800GTX's once I sold my last 8800GTX.

About time someone spoke the truth around here rather than repeating something someone else said. Bottlenecks are seriously over rated.

You run the resolution as high as possible and stick as much eye candy as you can throw at it. The title then becomes GPU bound. And to be fair you don't do SLI /TRI SLI or even Quad SLI on a small resolution < which is entirely what bottlenecking is. A low res makes it become CPU bound. Which in turn you have to increase CPU speed to get around it.

To an extent you are correct but you are also incorrect.

The term bottlenecking in the graphics world refers to how fast the CPU can pass the information to the graphics cards.

If your CPU is not fast enough to feed them 3 cards with the information they want in time and in tandem then there is going to be a performance hit and this is what we call the bottlneck.

People forget that everything inside your PC apart from the PSU is fully reliant on the CPU for its data... Regardless of what resolution you are running.

A true CPU bottleneck is rare though. I have a thought in process that I still need to verify, but I am starting to believe that in many cases when people think there is a CPU bottleneck, it actually is an FSB bottleneck. This thought is based on a thread in which a member had a higher 3DMark score with a set up that had a lower CPU clock with an higher FSB as opposed to higher CPU clock with lower FSB. Current CPUs are so powerful that they should be able to handle the GPUs... however, the FSB seems to be lacking.

Again, thought in process and no proof (yet).

Yeah could be. But at the same time I run a 1440FSB and get no different scores to when I run 1600FSB.

find it kind of funny that all you asked was a just out of curiosity question,and every one went off telling you what you needed to change about your rig.

really people, just answer simply 1000 watts or higher, the end.
