Yeah, I agree with dunerider5 on this one, and with optical mice, you don't need mousepads anyway...and that one is very expensive.
I have a Microsoft Optical Mouse and it does me fine, adn is also good for games, though of course, wouldn't be as good as the logitech if you do alot of it.
I agree with the processor, with the updated Venice core very much
I also agree with the video card completly. Overall, a great system mate
i hope this helps
