[quote name='thebrig' post='1151958' date='Mar 6 2011, 10:11 PM']First thing I'm going to do is install windows7, 64 bit version, after speaking to a few computer boffins, they seem to think it should make a big difference to the performance, and it would allow me to add another 2GB of RAM if needed.[/quote]
Does your hardware support the extra ram?
The OS will but thats only if the motherboard can take it.
Just something you may wish to research before purchasing.
