Best computer for $1000

This is what I found the best for this prize. I have calculated like 800€ which is about $1000

CPU: AMD FX-8150
GPU: AMD Radeon HD 6950 1gb
Hard disk: Seagate 3.5 Barracuda Green 2TB SATA600 5900RPM
RAM: Kingston 4GB DDR3-1866 CL9 x 2
Motherboard: GA990FXAD3
Case: Antec 902 or NZXT Tempest
Power: 650 o 700W (still need to sum all the wattages).

After checking a lot of reviews I think this is the best for the money I want to spend. Do you think something could be changed? I won't mind adding some money for a relevant change.

I would really appreciate some expert opinion because I'm going to spend all my money on this :-) If I should change something just tell me, I will take very seriously any kind of commentaries or impressions, and I'll study each case in detail.

Thanks a lot community!

Do you think I should consider having an extra SSD hard drive for the boot etc..? Does it deserve the price? What is it going to work faster?
