Indeed, the emulation costs some ressources, since you run the following stack: Windows/Virtualbox/Linux/Sage.

Ubuntu and windows are not platforms but exploitation systems that can run more-or-less on the same platforms. So it does not makes much sense to buy a new computer to run Ubuntu (or any GNU/Linux distro) on it. Instead you can:

• Replace windows by Ubuntu (say) on your existing computer, in case you do not use windows-specific software.
• Install Ubuntu on a separate partition, so that you can boot on both operating systems.
• If you do not want to touch your hard disk, you can boot from a live-USB containing Debian GNU/Linux and Sage and run Sage from there. See http://www.sagemath.org/download-liveusb.html Note that in this case, Sage is built to run on both 32bit and 64bit systems so that even old computers can run it. Hence you might lose some performance compared to versions of Sage compiled for 64bit systems, i am thinking on building such 64bit only live USB.

Out of curiosity, could you send us the code you are trying to execute on your computer ? Sometimes, tuning your code is more efficient than buying a newer computer.
