PREFERRED WEBSITE(S) FOR PARTS: Newegg

COUNTRY OF ORIGIN: USA

PARTS PREFERENCES: I'm more familiar with Radeons at this point- am I missing out by not looking at GeForce more closely?

OVERCLOCKING: Not at this time, maybe down the road (with additional cooling etc)

SLI OR CROSSFIRE: I would love a card that I can get a second one of in 6 months when i have the cash to make this thing a BEAST

MONITOR RESOLUTION: Current is 1680x1050, might upgrade down the road

ADDITIONAL COMMENTS: Along with a possible upgrade to Crossfire/SLI, I would love the option to run dual-monitors (More for productivity apps than gaming). My hand is being forced to build this sooner rather than later, so I'm trying to get a gret build for now that, when I have the cash, I can make an AMAZING build with a few upgrades (RAM, Second Card, SSD Bootdrive, maybe overclock with additional cooling).
