I am guessing you mean GT630 or GT430. ..
An i3 generally is not found inside the PC that is needed render or constantly export video files. ,As far as I can fathom.... an i5 would be fine for that given the price point. Though an i3 4130 is a great CPU, Capable gaming CPU , Fast single-threaded performance of haswell, And Hyper-threading allows the Dual core to have a bit more room as far as multi-tasking and using applications that or more heavily threaded.
i can tell ya that if your looking to build a budget Gaming/Editing PC than 2 out of 3 people will say go for the FX 6300 and asus m5a97 r2.0 as the value is unmatched , and I agree with that. Though i would opt for a 990FX in that case( ga-990fxa-ud3)
As far as Graphics go...
