I am looking to replace a Windows 7 machine, already have a new macbook air and want to keep moving to the mac line. For my desktop, I MUST install Windows 7 back on it, parallels, etc. So that will have to go on this mini, whatever version I get. I don't play games, ever, so graphics are not a worry for me. The most is surfing the web, using the VPN back to work, nothing very intensive. Is the basic mini ok or would it be better to bump up to the 2.5 with dedicated graphics card? I am going to bump the ram to 8gb no matter what. The hard drive speed doesn't need to be lighting fast, I can add an SSD later on. Main question is it worth the cost to go from 2.3 to 2.5 and the dedicated graphics? Thanks!
