both of them are the same, if you're going to multi task a lot, better take i7, if not, just go with i5
for the graphic, you said that your boyfriend want a good graphic, good graphic : more expensive
8GB ram is enough, based on my experience, dont know bout others 
For the HDD, up to you

You asked for a multimedia PC without stating extra information, so I assume it is for gaming (for your BF), movies, browsing and etc which aren't CPU demanding at all so I went with i5 instead of i7, i7 won't benefit you for those tasks listed unless you are going to do video rendering/editing etc.

You said you must get a good graphics card for gaming, so I included a high end GPU for you, please bear in mind GPU price is always > CPU price, consumer grade i7 costs at most 1.6k but consumer grade GPU can go as high as 4k (and more).

As for RAM, same thing as well, you didn't state what you are going to do with the PC, for basic stuffs (even gaming), 8GB is enough.

1TB HDD is the standard nowadays, 500GB is just around RM 20 cheaper than 1TB which isn't worth at all. Game/FHD movie file size is getting bigger and bigger nowadays, 1TB HDD is just barely enough TBH.

External HDD normally comes with 5,400 RPM only which is slower than internal HDD's 7,200 RPM FYI.

You left roughly RM 220 with this build, Revit does use GPU but your budget can only fit low end GPU (GT730) which isn't really worth to spend on it currently, you can either use the money to get a 120GB SSD now or save the money first and get a more powerful dedicated GPU later when you have more funds.

What would you recommend if the budget being stretched to below 3k?

Thanks

You can add Palit/Zotac GTX750Ti and 120GB SSD.
