APPROXIMATE PURCHASE DATE: The coming summer months
BUDGET RANGE: Under $900 unless there are too many good parts I just can't ignore. Pretty much set on that limit though.
SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming. (max settings on recent games at a reasonable resolution, ie: no more than 1600x1200, I've been used to the lowest setting for every game on my laptop and 7 year old desktop) As long as everything else isn't terrible, I don't mind.
PARTS NOT REQUIRED: monitor, speakers
PREFERRED WEBSITE(S) FOR PARTS: newegg.com, unless price and service are matched/surpassed with others.
PARTS PREFERENCES: none really, as long as they're good, reliable parts.
OVERCLOCKING: Maybe SLI OR CROSSFIRE: Maybe
MONITOR RESOLUTION: 1600x1200
ADDITIONAL COMMENTS: aesthetically, it could be a vomit-colored brick, as long as quality and reliability are second to none for the price.
I've looked around and put together a wishlist of parts, but still value any and all input
If you're going with AMD, you should probably stick with ATI for graphics as well. I'd upgrade to a Gigabyte 790 FX motherboard and grab 2 XFX 4850s (you could go for the cheaper 4770, but I'd personally rather have the 4850s). That processor should be great.
I believe you'll need DDR3 for the AM3 mobo, so get a 2x2GB kit made by G. Skill.
As far as a case and PSU: Cooler Master and Antec make excellent cases - and Corsair's 650 TX PSU is excellent value at $70 AR.
With this build if you know you plan on overclocking you can add a cpu cooler and upgrade to 1066 ram. I didn't include OS because if I'm not mistaken Windows 7 is free. Even if you don't want Windows 7 there is still wiggle room for Vista. In addition alot of items on the list are free shipping, saving you even more.
If you don't prefer crossfire and want to drop the price a bit you can take a single 4850 and then drop the 650w to a Corsair 550vx
