AAAHAHA I dont think so. My GT is not only flashed to Ultra and OCed beyond that but i also have 4 more pipes cranking then the GS. I think you need to redo your math man.
Nah, it's true. Assuming you get a nice overclockable GS, it can indeed beat out a GT regardless of how high your overclock is.....I mean of course unless you're doing serious volt modding and LN2 cooling or something, but under normal circumstances is what I'm referring to.
Even with the lack of pipelines that GS can be overclocked like mad and infact beat out our GT's. Mine is at 450/1200 personally and yes some GS's can infact beat those. The flashing to Ultra really doesn't do anything except increase chances of your card dying since it puts .1 extra volts through it and it's not necessarily made to handle that. Beyond that some argue that the GT infact has tighter memory timings, however, as to what they are I couldn't tell you because the Vram memory timings are nothing like a regular system memory's timings.
But yeah........overall as lame as it sounds, the GS even with 4 less pipes, it's overclockability on some of the cards is ridiculous (on the PCI-E) and will infact beat our cards. I know it sucks, but it's true.
