gaming computer, fatality and duel core

Hi all first time poster and older computer builder. Its been awhile since i have built a machine and i am wanting to build one now. I have read some information and most people say that SLI and Crossfire type technology is not really that good if you are willing to get one really good card. I was also reading is this section about duel core chips and if they are good to have no and for future, i saw some mixed ideas but anyway. Here is what i am looking at if anyone has recommendation please let me know.

Abit fatality an8 mobo
socket 775 duel core (don't know speed)
for graphics one of the new x1900 cards

Is this good for the main components or should i be looking down another road. I mostly play mmorpgs and some fps's like COD.

thx

I think you should count memory as a main components... 2gb should be enough for gaming... I think manufactor depends on personal liking... if your not fps horny

im with him on the overpriced part.
look at all manufacturers. like asus, dfi, other types of abit boards.

if you want good a good pc wait as little bit for the socket m2 to come out and do get sli with it there is a major difference and you get 15 more fps in fear my cuz has one and its awsome and also do get amd but wait for m2

i think that at some point, they started to talk about 939s, only not everybody was on the same page
