Budget PC build upgrade under $450?

Hey there,
Right now, I’m running an Nvidia GT 640 along with a 1TB Seagate BarraCuda.
I'm looking to put together a build that leaves room for a future upgrade to an Intel Core i5, complete with an SSD and a beefier graphics card. Ultimately, my goal is gaming (though I don't care much about high FPS or ultra settings) and music production using Ableton Live paired with an external sound interface. I was thinking of basing the initial setup on something like an Intel Pentium G3258.

Since I want this rig to last, I'd rather invest in a solid power supply and a motherboard with four RAM slots that fully supports Windows 10.
I'm also wondering if it makes sense to jump straight to a Skylake G4400 instead. How would that stack up against the Intel Pentium G3258 when it comes to the tasks I mentioned?

Thanks in advance,

1 x Intel Core i5-4460 Processor (3.20GHz, 1MB, 6MB, 84 W, LGA 1150) Box
1 x Asrock B85M Pro3, Socket 1150, supports 4th Gen Intel Core i7 / i5
1 x 8GB DDR3 (1x8GB) Kingston HyperX Fury, 1866MHz, CL10
1 x Zalman Z1 mid tower case. 199(W)x432(H)x457(D)mm. Standard ATX
1 x Fortron 550W Raider power supply, RA550, with 12cm fan

$1042 ADM

The build Smartic put together for you is fine. You get the i5 right out of the gate, then just toss in an SSD whenever you have the cash...
