But the percentage difference in frames is the important part. Just because the numbers get smaller the higher the res, the percentage difference is still there. And you can see the catastrophic difference between the 8350 and i5 in cpu bound games (Those include Crysis and Assassin's creed by the way). The i5 is not much more expensive than the 8350, but guarantees a massive improvement in CPU bound games, as well as a good percentage difference in GPU bound games.
You asked for opinions and advice, you have been given them. It would have been advisable to mention you simply don't want to buy intel hardware in the forefront, because I personally cannot understand why you "hate i5's" judging by the fact the motherboards are the same price, offer more features, and are only $20-30 more expensive for the chip, but offer such an improvement in all areas bar file compression and encoding/decoding.
If you don't want to receive advice on your choice of AMD processor, remove it from the original discussion, because everybody will tell you to change that Athlon. I have no problem if you want to go with AMD processors, but the 8350 is a minimum spec for 4K.
