CPU - The Phenom II X4 955 will overclock exactly the same as the 970. If you are sticking with stock speeds you are fine with the 970. If overclocking, save a little money and go with the 955. Don't forget an aftermarket CPU cooler.
Motherboard: ASUS LGA 1155 Intel Z68 DDR3 2200 SATA 6Gbps and USB 3.0 Supported ATX Motherboard P8Z68-V
Same as the other one just cheaper I suppose
RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Profile Desktop Memory Model
Case: Antec Nine Hundred Steel ATX Ultimate Gamer PC Case (Black)
Thought I might as well upgrade the case if I'm gonna spend this much.
Hard-Drive: Seagate Barracuda 7200.12 1 TB 7200RPM SATA 6Gb/s with NCQ 32MB Cache 3.5 Inch Internal Bare Drive ST31000524AS
The third one down you told me sadams04
CD/DVD: ASUS 24X DVD Burner - Bulk 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM Black SATA Model DRW-24B1ST/BLK/B/AS - OEM
Power supply: CORSAIR Enthusiast Series CMPSU-650TX 650W ATX12V / EPS12V SLI Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply
EVGA GeForce GTX 560 Ti Superclocked 1024MB GDDR5 PCI-Express 2.0 Graphics Card - Lifetime Warranty 01G-P3-1563-AR
Also the same as above but Superclocked and I guess not quite a gigabyte. Could that be a problem? This one I found cheaper than the other somewhere.
GPU - That EVGA GTX 560 Ti Superclocked GPU will be fine.
PSU - The Corsair 650w is fine, but as JackNaylorPE said... the XFX 650w is better buy. Both have the same great quality and efficiency. Consider that swap for a $40 savings. (sorry... this is something I should have noticed earlier.) http://www.newegg.com/Product/Product.aspx?Item=N82E168...
