This isn't a matter of simply pushing the clock and gaining peformance that was wasted. A system that ALWAYS stalls at the frontend because the pipe is full cannot gain the lost performance back by pushing the clock. If you push the clock, you will still fetch and retire at the same relative rate that you were before and still cause stalls. It is true that pushing the clock will increase performance, but it won't solve the problem of the originally wasted cycles.
From the article - "Because of the length of the pipeline and the latencies of sampling textures it is possible that the pipeline is full before the first quad reaches its end. In this case the Gatekeeper has to wait as long as is takes the quad to reach the end. Every clock cycle that passes means wasted performance then. An increased number of quads in the pipeline lowers the risk of such pipeline stalls."
I understand that the article writers are trying to come up with reasons that the Nvidia part is wasting performance, but this doesn't make sense. No architect in this right mind would ever design a pipeline that becomes full before the first instruction can exit. The means that you are fetching much faster than you are retiring instructions. That means you will always have a pipeline stall at the frontend and you will always be wasting cycles. I think the designers would have checked something like that. You can't afford pipeline stalls to happen regularly.
In all the dorms here at UofI, they are disabling the data port by default. If you are bringing a computer to campus, they first have a tech/RA come by to your dorm room and run some basic Symantec tools to see if your system is clean. Once they check that and make sure you are patched, they enable your data port. I didn't mind not having Internet the moment I walked in because I knew that I wouldn't get the virus from someone else.
...and last time i checked service is better than no service. And please don't say that my family will be able to get on IRC and get help there. Usability is much more important than $50-100.

If you haven't watched Office Space, you are the one with some issues.

if anybody has any experience with the tech workers in india you will get the point."
And mod my parent up if you like to generalize!
