If you see a part that should be upgraded or doesn't fit please tell me a good alternative or a close competitor. Suggestions will be appreciated. the only thing i am not sure about is the power supply.it will be for gaming and video editing.it is at the top of my budget so any way if u could think of another part to bring down the cost.
NZXT Phantom 410 Mid ATX Case Gun Metal Finish
Samsung 22x SATA DVD-RW
Cooler Master Hyper 212 EVO
Intel Core i7 3770
Seagate 1TB SATA
ASRock Z77 Extreme4
Thermaltake TR2 Bronze 600W
G.Skill Ripjaws X 8GB(2x 4GB) DDR3 Memory Kit
Gigabyte AMD Radeon HD 7970
Anti Static Wrist Strap
windows 7 Home Premium Single Pack - OEM
That PSU is from Thermaltake, not a great PSU maker. Look to Seasonic, XFX (rebranded Seasonics essentially), Corsair and Silverstone for good Power supply's. Make sure its modular and 80+ Bronze or better.
Also 600W wont let you run SLI/Crossifre, just be aware of that.
another thing to take note of is that there isnt a point of getting a z77 board if you are not overclocking. just get yourself a h77-v from asus as it has the same features if not more than the z77 version minus the overclocking. plus im dam sure its cheaper than the extreme4 board
