ask yourself a few questions

1) are you under 14

2) ms said gamers dont want wiis after they turn 14 so are you kiddy ?

3) is ssbm really better then halo 3 ? 

heres a quote from some important guy at sqaure.

"we at capcom want to maximize sales and that means were putting it on the 360 we hate fanboys and think they should be shot" 

ok look. here are some tips is suggest you follow them if you want to be able to upgrade properly in the futer...

1) buy a really good case preferably a full tower because videocards are getting big now adays and your gonna want the extra space.

2) if you have enough money buy 2 sata HDDs around 320gb each this will insure future space. also sata has small cables then ide so ur get better airflow.

 3) make sure you get either a socket 775 or am2 mobo there are some good budget ones out there shop around.

4) you only need 1 type of ram which will be ddr2 make sure its all the same speed brand etc for best perfmorance, start with 1gb

5) wait for the much cheaper dx10 cards to come out and get one of those

6) you need atleast a 550 watt psu with dual rail technology or any future upgrades will not work.

 7 ) make sure the cpu you buy fits the socket of your mobo.

quad core sucks for gaming and why are you upgrading to dx10 now when you get better perfmormance on dx9 wait a year and save yourself alot of money...

oh also x-fi is crap sound quality it sells off of the fatality name get a audigy or the extreme version save money.
