I plan on building a gaming pc for christmas and if anyone on the site has already built a pc that knows a thing or two about components could help me that would be great. Here is a list of the components I'm would be using: Case: COOLER MASTER HAF X Hard Drive: Seagate Barracuda 1TB 7200 RPM SATA 6.0Gb/s Motherboard: ASUS Crosshair V Formula AM3+ AMD 990FX SATA 6Gb/s USB 3.0 Video Card: XFX HD-687A-ZDFC Radeon HD 6870 1GB PSU: COOLER MASTER Silent Pro RS850-AMBAJ3-US 850W CPU: AMD Phenom II X4 965 Black Edition Deneb 3.4GHz OS: Microsoft Windows 7 Home Premium SP1 64-bit - OEM Heatsink: COOLER MASTER Hyper 212 Plus ODD: ASUS 24X DVD Burner Memory: CORSAIR Vengeance 8GB (2 x 4GB) DDR3 1600 Total Cost: $1150.10 Since I'm 16 I'm a bit strapped for cash but I'll have this amount plus a little extra for my first iPhone (C Spire unlimited data FTW) , but I plan on adding another 6870 to crossfire later. I plan switching from console gaming to pc mainly because of games with a heavy modding community like fallout, oblivion, and in the near future Skyrim . This is going to be my workstation from now till (I hope) 10yrs (upgrading along the way) Any building tips would also be greatly appreciated. Later during christmas my senior year in high school next year I should be able to scrounge up enough to buy a base model macbook pro 13". My final question is if having a beast of a desktop would allow me to skimp on my laptop's performance and still have a good computing experience?
