The list author says: "Why build a cheap Gaming Rig that will only allow you to play games on the lowest settings. This build will let you play everything maxed out and use Intels new Sandy Bridge combo and Radeons new 6800 series graphics card. it cost a little more than your $550-$650 build but not by alot"
"The HAF 922 is a solid choice for a case excellent air flow and pretty big for a mid size case. you could opt for the HAF 932 but play $60 more for a case that's only 2 inches longer an inch short and an inch narrower. Nah not for me the lossing 2 inches on the 922 will still hold the biggest of graphics cards out there"
"this will be plenty of power to run your rig it will handle everything you can put on it it will even be able to handle the 6950's in a crossfire you could even drop down to the 650tx which goes for $90 if you watch on the 750tx it will drop to $100 so watch for that."
"this will be your backbone here, and it will do just fine it's rocking the new LGA 1155 socket giving us access to the new sandy bridge chips, and it gives the option to run crossfire. They also feature the new UEFI bios screen check it out."
"HIS has the best Radeon 6950 performance wise its not as good as the sapphire on wattage (HIS pulling around 130 watts) nor does it have the cool decal on it. while it won't look as good in the case wait till you see her performance on screen"
"this is a nice start 640 gigs is alot either way you flip it plus being a Western Digital Black you get the 7200 rpm pretty quick. you can get a separate SSD drive to but you OS on but that's to deep for my pockets"
