Why can't this pc Handle AC4 Black Flag on ultra?

[Kaynejoinedtsh]

I have these specs

Intel Core i5 760 @2.8GHz
6GB RAM DDR3 4GB and a 2GB stick.
Sapphire R9 270x Toxic GDDR5 2GB
Intel DHPPHC Mobo
Windows 7 64 bit
500W PSU

Can I play the game on ultra if I upgrade the pc like this..

Intel Core i7 4770k @3.5 GHz
8GB Ram Kingston HyperX
Msi Z87G45
An SSD
Same Gpu

And do i have to upgrade the 500W PSU too?

Thanks any help would be greatly appreciated.

Thanks for the answers.

PSU is only few weeks old And the res is 1366*768

Yes you would be able to. Depnds on if you are going to do some over clocking or not, but how old is the PSU. If it is 4/5 years old it might be time to upgrade it.

what resolution? 270x might not handle ultra
