But thats up to you if you want to get a pre built pc.
It all depends if your going to oc or not.
And do not get the 8500gt if you plan to game, its not worth the money.
You would be better off getting a 7600gt.
I am hating dell at the moment since they delayed one of my shipments untill the 16th of september so I just cancelled it. IT was a big hassle though.
I just got the e6550, and a good mobo, so im excited to get it and find out its potential.
I play games now and then, and if a good MMO comes out anytime soon I'll probably being playing that too, as for a 7600 I want DX10 support, so I can't really go with that, and I don't want to be paying all that money extra for an 8800.
