I would go with the AMD side, not because I'm an AMD fan-boy but because the card+CPU are better that the i5+760 in most of everything. If you want you could go with the i5 and the 280x. Nothing is stopping you from doing that. The AMD processor, though, has 6 cores vs. 4 in the i5. So in the end, it is all up to you whether you want to go AMD vs Intel, or AMD vs Nvidia.
