Your power supply has plenty of room for 8-core overclocked and even for more power hungry GPU, no need to worry about that. The FX9xxx are always bad deals. They are intended for people that "can't overclock on their own", because they are tech-unsavvy and can't enter BIOS. Or for people that want more guarantees that can hit 5Ghz. Otherwise, most 8320 and 8350 can hit 4.7Ghz. The "smartest" deal, would be to get 8320. But if you want 4.7 at all costs, the 8350 is probably more "secure". The 8320 should do 4.5Ghz even for a mediocre chip.
The newest chips (8370, 8320e, 8370e and the rest of 95w 8-cores) are usually able to overclock at lower voltage. But for the "e" there might be problem to go reliably over 4.5Ghz. The 8370 should be more guaranteed to do that. But again, you 'd have to email ASUS and ask about BIOS support for these.
Otherwise, like i said, 8320 is the "smartest deal", with a certain risk about whether you ll achieve 4.7Ghz, 8350 should be able to achieve 4.7, unless you get a very unlucky chip and your BIOS supports them certainly.
I wouldn't buy 9xxx under any circumstances. It's just wasted money for those that can't hit F2/DEL to enter BIOS and raise a multiplier and a VCore and run some stress tests.

Also will upgrading from a 1090T to a fx 8350 be worth the money for performance and better oc capabilities?
Look, in applications that use up to 6 cores and don't use new instructions, a 1090T core at 4Ghz, is roughly equivalent to an FX core of 4.4Ghz. You will see an improvement, but now like "wow!". Where you will definitely notice improvement, is in applications that use newer instructions that only the FX support (like AVX) and in applications that can load all 8 cores (you will get something like 25% certain gain in things like x264 or folding@home and such stuff). Games also tend to benefit more than what i described, since they appear using more modern instructions.
I also have a 1090T and went first to FX6300 and then to FX8320. I was always at stock. The big difference i saw it with the 8320, when i did x264 encoding. My regret is the 6300, but i bought it for the reduced TDP, so at the end it's ok.
1090T--> 8350 won't be a huge step in ordinary tasks, but if you encounter an application that can use all 8 cores, you will definitely notice a big difference.
To get an idea of relative core strength, see this comparison at stock speeds:
1090 at 3.2 vs 8320 at 3.5:

^ As you can see, the performance gap goes to 20%+ in cases where the benchmark is multithreaded, so the extra 2 cores, count roughly as 2 enitre additional Phenom cores.
