Not everyone will get 2.8 and like Seer said you will have to use a divider. There is no point in spending money on ram like that. You get very little improvement. If you want to spend the money get a low latency ram instead. Ram speed matters very little.

Robert, please research a bit on the speed thing. A bit of googling would've led you around...

Check out AngryGames' post @ DFI forums. He ran dozens of tests with different RAMs at different speeds, with different dividers.

The general results are:

Speed over timings (Unless it's 264 3-3-3-8 vs 265 3-4-4-8)
Dividers don't matter
2T is almost irrelevant (~3-5% performance drop at the most)

3-5% is about all your looking at for a gain in ram. If you run at 2T you lose anything you might have gained from good ram. Let alone if you use value ram. So if 2T if irrelevant then so is using high performance ram.

I agrre dividers dont matter.

To get the same boost as you get from Cas 3 to Cas 2 takes quite a large increase in speed.

What is running at 2T?

You wont have to worry with you ram. Its part of the timings that isnt as widely known about. You have the option of 1T or 2T. Mostly you have to be running 4 sticks of ram but there are other cases.
