Alright I admit to be a newby to this site's forum, but not to computers. I am however taking on the daunting task of a first build. It looks like this:

My Question:
Which memory would be a better match for this system?

CORSAIR Dominator 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
-or-
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)
-or-
CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)


Any suggestions are welcome, regarding my system. Thanks for your time...:cool:

If your going for a pretty high oc (something like 3.8ghz), the Dominator ram, if your going for a high oc (like 3.5ghz), the DDR2-1066 XMS2, if your thinking about oc'ing and just need some good ram, the XMS2 DDR2-800. Although if you can afford to get the expesive Dominator ram thats the stuff you should even if your just shooting for a mild oc, better ram is better ram.
