Missed that, my bad.
Also the Seagate drives have a higher failure rate and I'd never get one. Also they aren't faster.
They are plenty fast. I never stated they were faster than the Caviar Blacks. However, they can compete. And every Seagate drive I have owned has performed well. Never had one fail on me. Been running strong for years. There's no reason to be brand loyal; especially when you can get double the storage for less.
Why are you even talking about 7950, OP stated he wants nvidia.
That doesn't mean we aren't allowed to offer suggestions and insights of our own. The HD 7950 is a worthy contender. However, for his resolution, it isn't necessary.
