Choosing memory clock rates latency

[blackspeedo]

im considering kingston hyperx 4gb (2x2) ddr3 2000 memory. i have been reading to get 1333 with low latency. the memory im considering is cl8 and 8-8-8. i can get this on sale for 90$ is this a good deal? my setup is msi gd70 with phenom II 955

CL8 2000MHz ram is theoretically 9% faster than even CL7 1600MHz ram, however even if you were to have massive amounts of low latency high speed ram, it still wouldnt boost performance a ton as most things are not bottlenecked by the ram. If you can get it for $90 i would go for it.
