Im thinking about upgrading my system and I just want to know if everything works together and what not.

G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 for $90

AMD Phenom II X4 965 Black Edition Deneb 3.4GHz quad core for $180

Radeon HD 6950 2GB 256-bit GDDR5 for $270 I think

And I think I am getting a 1920x1080 21.5inch monitor for $150.

and I have the Gigabyte GA-H55M-UD2H motherboard with 2 x 2gb of ram stuck on there, I think I have a 700watt power supply and the Nzxt Lexa S case. So yeah just let me know if you think that will work all well and stuck if you think its a good deal and other things like that.

Thanks
