Yes you can run that RAM fine on your motherboard.
However,2000(O.C) doesn't mean that its capable of OC'ng,it means that if you use a DDR3 2000MHz RAM,then you have to set the timings,speeds and voltage manually in the BIOS.
Agree w/Maziar and to answer your question on suggestions on RAM I would suggest going with a good, reliable company with a well-designed heatsink is really the way to go. Companies I trust would include: Corsair, Kingston, OCZ, G.Skill, Mushkin, and Patriot (although not in that order).
The one you went with G.Skill Ripjaws are not only really good. Other series that are similar in terms of performance and price are the Corsair XMS3 and OCZ Reapers.
There are all the options although I went with the RipJaws and nearly a year later I have not had a complaint.
