Well yes, the speeds you listed would definitely run faster, but since all memory sticks act in different manners, you would need to try it out to test for stability.
It may needs a little more VMem to get lower timings, but the timings you listed should work great too :)
Doesn't affect all boards, but it does affect many when trying to increase above 1300MHz FSB with a Quad Core CPU.
Also, the difference between the AR/TR is the packaging and warranty, the actual boards are identical though.
Core 2 Duo users will be unaffected, in our testing, the overclockability of Core 2 Duo's remain the same, this update affects only Quad Core CPU FSB speeds. (around 450MHz FSB for Core 2 Quad CPU's)
I would recommend to get a replacement on that, you can go to our website, or send me an email at jacobf@evga.com to get a replacement. Make sure to put the original HSF back on before sending it back in though.
Thanks,

320MB of texture data would never be a bottleneck, however, for future games with higher texture resolutions it may be...
Most games now fit perfectly fine int 320MB of texture memory.
