Good choices for the most part. Most people would not want a recertified HDD but since it is strictly for games, will probably be okay. Just keep backups of your game profiles.
That graphics card should not disappoint.
Review comparing Athlon II X4 640 versus Core i3 530
Note that the Core i3 was a touch faster in games even though it was a slightly lower MHz and merely a dual core compared to the Athlon II. The Core i3 550 would be even faster, plus Core i3 chips will probably hit higher overclocks and use less power. Their TDP is 73W versus 95W of the Athlon II, plus some of that 73W is the graphics core which will remain unused.
On the flip side, no denying that the Micro Center bundle is very inexpensive. Here are a couple suggestions:
Consider the Asus M4N68T-M V2 instead of the M4A78LT-M LE. The reasons are that it supports core unlocking and 125W CPUs. The M4A78LT-M LE only supports 95W CPUs, meaning the CPU VRMs aren't as robust. It also costs $10 less.
Now, core unlocking doesn't do anything with your Athlon II choice, but for $4 more you can get a Phenom II X2 560 Black Edition. Black Edition means multiplier unlocked, plus it is a dual core that can be unlocked up to 4 cores. Note that this is luck of the draw - some have had great success while others have not. Even if it doesn't unlock, it has 6MB L3 cache plus 300MHz higher than the Athlon II. Additionally as a dual core it has a TDP of 80W (note this goes up when you unlock cores).
