I'd look at what your software requirements are (minimums) and what the recommended specs are. Different RIPs will be able to make use of different features more effectively than others can. Is your RIP software up to date? There have been some improvements to the software.
But as pointed out, most computers that can run Windows 10 will be able to handle any decent file. I regularly RIP off of my 8 yr old laptop, it may take a while on big files, but it's never failed, unless the file was the problem. Also some RIPs have file size limits. Are you exceeding the limits of your RIP software?
There's a bigger picture to look at. Don't just throw a new PC at the situation (unless you like new PCs)
Good Luck
