Very Very Impressed With Performance

Comments: I had the neighbor kid come to me with $400 to build a gaming system for WOW he was running an integrated Nvidia 6150, 1gb DDR2, and a first gen dual core. IT WAS HORRIBLE TO WATCH!! We chose this chip, 4gb G-Skill ddr3 1600, Biostar A880G+, and a GTX260 on sale. This was the first AMD machine I have built in at least 2 years. I will say I am impressed with price versus performance with AMD they are great with that. Now if they could only release an enthusiast chip that will surpass or at least fight against a current intel enthusiast chip. 8 core FX is a flopp.

solid cpu

Comments: I don't do much games but played TF2 on it with onboard video (radeon 4250) without problems. Also, playing HD movies at 1080p without any problems. CPU usage at 35% on HD movies. This CPU handles what I needed well.
