Hi everyone.


Im planing on building:


AMD Phenom II X4 965 Black Edition, S AM3, 3.4GHz, 8MB Cache, 125W

ASRock 970DE3/U3S3 (Socket AM3+/AMD 770/DDR3/S-ATA 600/ATX)

LEPA B650-SA 80PLUS Bronze PC Power Supply

EVGA GeForce GTX 560 Ti 900MHz Graphics Card PCI-Express 1GB HDMI SuperClocked

Corsair 8GB (2x4GB) DDR3 1600MHz XMS3 Memory Kit CL9 1.65V

Seagate Barracuda 250GB 3.5" SATA 6Gb/s 7200RPM 16MB

and I've got one question only; Is this going to work? Its not going to explode or anything?
its my first build so I want to be sure.
I know how to build a desktop I just need to know if its going to work well together. Eg, do I need to invest in the better cooler for the cpu?

thanks Guys you are awesome!

all the parts you have chosen work very well together and there is nothing wrong with your system but i have put together a system for you that will dominate this quite easily and for the same price. and i have included a case and other parts.

Here's the full list: http://pcpartpicker.com/user/CrazyDaveGaming/saved/2dJ5

This system has 8cores and will be about 50% more powerfull and i could include a case more storage better quality motherboard and a cd drive.
