Building first amd comp, need feedback

ok, this is the first amd comp i will be building. i just need some feedback and tell me the pros and cons of it, if someone will be kind and do so. Also take in mind i only really play games. Mainly Dod source, and Counterstrike:source. I encode some movies now and then, but gaming is my main priority. so here it is

http://www.newegg.com/product/product.asp?item=N82E16813131524 ( I've never used asus, always been msi guy. but i hear asus is better for overclocking so i picked this board, plus it has the 2sli slots i will eventually be using)

http://www.newegg.com/product/product.asp?item=N82E16819103497 ( i was lost on what processor to go with, i didnt know if i should try the X2 processors, but i thought i read somewhere here that the X2 processors arent very good for gaming, and thats why i chose this one, i dont know much at all about amd processors though. will this one be fine for gaming? i was reading some, and i saw some people mentioning the opteron for gaming. anyone shed some light on this for me?)

I already have a good psu to use for this system, aswell as 2gigs of ocz ram waiting on it. any corrections or suggestions anyone can make? anyhelp is apprciated.

well if you got an opty like the 165 it would be dual core, have twice the l2 cache,you can oc it to at least 2.7ghz and it would be a bit cheeper. mine works perfecr for games. i play alot of cod2 and aoe3. also if you really want to get a good overclock i would get a dfi.

Dont get the regular a8n-sli, either get the a8n-sli premium or a8n32-sli if you want to go asus.
