Arguing that you "may" be able to overclock the 275 to speeds that beat the 1ghz ATI card is really besides the point. Unless you can buy an overclocked model that beats a 1ghz ATI sku, its really pointless.
Maxed out 275 vs. a maxed out 4890 http://www.anandtech.com/video/showdoc.aspx?i=3575&p=7






As for overclocking a 275 GTX significantly past the point in this review, I doubt it. You may hit ~720 core, or 1700 on the shaders, buts thats what, +2%. Memory is tapped. My GTX 285, for what its worth, maxes out 702/1600/2.7ghz for stability under Furmark, and the consensus from 275/285 owners is that GT200b is pretty much tapped out at ~ 700 core, unless you're volt-modding.

And like I said, 4890's are cheaper. You can pick one up for $180 on newegg right now, and I've seen as low as $150 recently after rebate.

Anyways this is a pointless debate. I've given my recommendation, it wasn't directed at you, nor do you have an argument about anything I've said. You're just trying to show me up since the last time you refuted something you didn't understand, and this isn't really the place for that.
It must be noted that these tests are run at 1920x1600. At this point you're entering into territory where GDDR5 will consistently outperform GDDR3. Considering the 4890 has to be clocked so high to achieve this given it's theoretical memory bandwidth the value isn't as great as it appears to be. Not to mention that most people do not have a display that is capable of this resolution (most have 1440x900 and 1680x1050). If you're into buying high end monitors with your high end hardware, you're not going to hang onto a GTX 2xx or ATI 48xx long anyways.
