I made fast tests in 2D on ARES 2x4GB Hynix CFR 2133 ( Double Side ) and Team 2x4GB Hynix MFR 2666 ( Single Side ). Both at the same ( quite bad ) settings, sub timings etc @2600 11-13-12-35 1N and [email protected].

It looks like there is some difference but mainly in memory copy transfer. Other transfers or latency are +/- the same ( sometimes up to 200-300MB/s better on double side sticks but thats nearly no difference ).
Total result gives us up to 2 secs difference in Spi32M ( depends from run it's 1-2+ secs ). Of course difference can be higher at higher clocks or tighter timings.
In this case I don't expect any difference in 3D.
Difference in memory copy is interesting but it's not affecting real performance so much. If you want to break any record then maybe it's worth to look for double side sticks but since real performance at 2133+ memory clock is almost not changing in daily work then I don't think it's key factor in choosing memory.
About that Vengeance kit. It's probably on MFR but I also saw Team Xtreem 3000 CL11 2x4GB Kit for ~$350 listed in some EU stores which is probably also on MFR. What can I say, Team's price is high but Corsair's is just a joke.
Main problem now is not memory that can make high clocks but IMC that can run high. There are maybe 5% of Intel IMCs that can reach that DDR3-3000 on ambient temps. I expect that when will be haswell premiere, we will see some higher clocked kits but so far it's hard to say if haswell will run without issues at 3000+.
