Well considering price...and I dont know how it is living over there in SA...I would go with the AMD build and save like 200 bucks. It will give probably about 80-90% performance of the Intel build, but your saving 200 bucks...and its almost xmas (if you do that kind of thing).
Plus it has a better video card.
If you want to wait....ivy bridge i heard is going to be coming around the Q2 of 2012 so that's a while to wait.
I made this question to myself some months ago, André. And I choose AMD. As we know, in Brazil our prices have some unfair taxes, which makes Intel settings much more expensive than AMD. It's like 1/3 of the price!
True that, but I don't want to risk buying an AMD mobo, and then 5 years down the line I won't be able to upgrade the CPU, seeing that AMD has stopped competing with Intel.
AMD has only said that it won't be there focus. Not that they would stop building processors. I bought a Bulldozer about 2weeks after the initial reviews because I wanted 8 cores in the future. Benches will get better.
At that USD price point the Intel build is typically preferred (P67 with i5-2500k). As others have pointed out the AMD system is still respectable and as long as you build on an AM3+ platform you have an upgrade path.
