Yep. DDR4 RAM is going to do wonders for igpus.
well listen, grab an fx 8320 for 150$ and a decent cooler for some about 40$ and overclock your fx 8320 to 4.5 ghz which will change it to fx 9370 and there it is REALLY competitive with the i7-4770... the A10 is great, but it will take some time to mature and become threaded maybe until early 2015, so It would not beat the FX line up in the first place, specially in well threaded programs with games like http://www.game-debate.com/games/index.php?g_id=4546&game=Watch%20Dogs
or engines like http://www.gamasutra.com/view/feature/132533/sponsored_feature_resident_evil_5_.php?print=1
which are heavily threaded, I wouldn't go for the 4 core A10 or i5-4670k to be honest, you are going to need something like the i7 or the FX 83--
my recommendation stays in tact if you want to overclock, if you don't want to overclock at all, go with fx 9590
