AMD FX-6300 Vishera / Asus M5A99FX PRO R2 AM3+: $234 before $20 rebate & $20 gift card
PowerColor Radeon HD 7950 3GB: $209 w/gold reward game bundle - before $30 rebate
Crucial Ballistix Sport 8GB (2 x 4GB) w/ Cooler Master HAF X Blue Edition: $238 before $10 rebate
That's the best stuff I've found, today.
The
Western Digital WD Blue 1TB is $70. The power supply is up to you.
Your have an upgrade path to CF that HD7950, and bump the CPU to an FX-83XX. AMD should soon roll out a 95w 8-core in the US (like the FX-8300) -- no one is currently talking about an AM3+ Steamroller CPU, but if one comes available, it should run on that Asus with a BIOS update.
That HAF case is nice -- but, you could easily save $100 there if you were so inclined.
