[QUOTE=NissanGQ4.2;791709]Worth putting in another drive win windows 10 on it or pretty much catch 22 for an extra 2gb?[/QUOT
The i5-2410M processor supports a 64gb operating system, so yes if you upgrade to 64 bit windows 10 it will support the additional ram. The best bang for buck upgrade you can do is to upgrade to an SSD, I'm not sure if your motherboard supports it though, I'd need the full model name to check.
Sometimes it's just not worth upgrading older computers.
