Theres the gist of my build i just wanna know how solid of a build it is and if there are improvements in parts that i could make. My maximum spending is $1800 and minimum is around $1500. I will probably need a keyboard and mouse and possibly a new monitor as well not sure if the samsung Syncmaster 226bw is compatible with the HD 5870. So final suggestions would be greatly appreciated i have obtained some extra cash this christmas and am looking into building a solid gaming rig thanks everyone!.
I disagree the new f3 spinpoints are much faster because of the 500gb platters. Also the corsair h50 performs AS WELL as high end air coolers... go air cooler IMO.
As far as your budget goes you MIGHT want to look into a i7 920 build if you plan to crossfire in the future simply for the 2 x16 pcie lanes. Anyway a single 5870 will rock at that resolution. A 750W psu should run 2 of those cards.
Motherboards, I dont have any experience with the p55 mobos so hopefully one of the brilliant minds that wanders these forums will help you.
Overall looks good and grats on the awesome build.
