This fall, I will be entering college for Computer Science, and I need a new computer. The laptop the school offers is good, but I could build a much more powerful (better for gaming) desktop for the same price, the primary difference being an NVS 5400m vs 2x 670 SLI.
Would it be practical for me to use Teamviewer or similar software to access my more powerful desktop from my old laptop during classes? Or is there a strong reason I should simply purchase the new laptop?
You can, but TeamViewer really isn't a great software. I'd prefer VNC over it. However, connection via TeamViewer is only as good as both the connection and the software. So performance-wise, you won't make good use of the 2x GTX 670 SLI when viewing it on TeamViewer or VNC.
