I'm planning on going full virtualbox ubuntu on windows 10 instead of having dual boot os due to some applications i need on a windows but I'm not sure of any significant difference that I might run into. I'll basically use the ubuntu for java programming, web programming and running some local servers. Will the virtual give me some downside on this, like affecting compile times and server startup? I have 8gb ram, i5-4690k if specs are needed.

You might want to hold off a bit since you have W-10 as host. VirtualBox is not really ready for it yet. That said I can not tell you about speed differences since I don't do windows, but I run several dedicated guest that perform various compiling tasks including video rendering which in my opinion is the hardest of everything on the guest. It is slower than on metal, but not that much and far cheaper than having a lot of metal boxes around to do the same tasks.

Ok thanks for the headsup, but windows 10 aside. I won't be doing some serious processes like 3d rendering. I'm looking more on the responsiveness/speed when multiple applications are opened, multi tasking(running servers, compiling, building) basic stuff development stuff also will it be as stable as a dedicated?

Like I said I do use the guest/s for compiling tasks too. I think it is acceptable as far as the speed goes, but it is not the same as on metal and never will be. Keep in mind that hyper-threading is not really the way to go. Use true cores and you will be fine. It has been my experience that HT is a poor man's way of trying to make it look like you have more cores than you do but it is just a sharing of the same core and nothing more.
