I need help I'm not sure if these parts work well together also if I dont plan to overclock will I need a after market cpu cooler??? And lastly are these parts worth it I will mainly be using this computer for gaming
Yes, everything is fine except for the 8GB too much RAM and the unnecessary i7.
Powerful video card, motherboard has good reviews, very high quality case and power supply, you could probably do better on the hard drive, but I doubt you'd notice. Traditional hard drives, much like optical drives have pretty much reached their peak in performance, (since there is inherent mechanical limitations as to how fast they can spin)
Probably not, RPM speed doesnt do much either. I have a SATA III WD Caviar Blue 7200 RPM as my main drive, and a Seagate Barracuda Green SATA II 5900RPM as my secondary. I put Windows7 on both, I can't tell a difference between them. Although, the higher cache of the one I linked like I said, technically should do something, but I doubt it would be noticeable.
