I'm sorry for the OFF but I do need to ask:
Shall I experience any performance improvement if I add a 1GB of RAM to my configuration of 3GHz dual Celleron/3 GB RAM/WinXP and switch to Win7? All that with an nVidia Sapphire HD6790 card.
It won't hurt. Mintcoin uses about .5 GB of ram on my windows 7 machine. And about 10-20% of my 1.4 GHz CPU. I can still game on it with Minting going on. Every little bit helps though.
