There are similar deals for inexpensive yet powerful gaming rigs this month. Below is an example using the new September deals.
Bargain Gaming Rig
CPU: AMD Phenom II X2 550 - $86
Motherboard: BIOSTAR A770E3 AM3 AMD 770 ATX - $55
RAM: OCZ Special Ops 4GB DDR3 1600 - $75 (after $20 rebate)
Video Card: SAPPHIRE Vapor-X Radeon HD 5770 - $145 (after $15 rebate)
Hard Drive: Western Digital Caviar Black 500GB - $70
Power Supply: OCZ ModXStream Pro 500W - $40 (after $20 rebate)
DVD Burner: SAMSUNG 24X DVD Burner - $18
Case: Rosewill CHALLENGER Black Gaming ATX - $45
Discount: $60 ($25 HD/Case, $20 RAM/PSU, and $15 CPU/GPU Combos)
This case looks like an amazing deal. It has great reviews, and the specs are impressive for the price. Also, the motherboard supports ACC, so you may be able to unlock one or two of the disabled cores on this processor. Note that if you need Windows, there's a combo deal with the motherboard for $10 off Windows 7 Home Premium, which would bring the total to $573.
I picked up a set of that Special Ops RAM last month, and it's been working just fine. It brought some stability to Starcraft 2, which seems to be a big memory hog. Speaking of SC2, here's my profile for anyone that's interested: http://us.battle.net/sc2/en/profile/1691667/1/Vypir/
