Is it worth upgrading my mouse?

[AFK_Matrix]

At the moment i have a Logitech MX510 and while it is a good mouse a few things annoy me about it. One is that the lead is starting to bug me lol as i have a wireless keyboard and its great having no wires. The other problem is how dirty it gets on the blue bits where i rest my hand!! Don't know if i have dirty weird hands or what lol, but i get like a grey scum devloping on the blue areas?? Its horrible and a pain to get off.

I am therefore looking at the Logitech G5 or G7. Obviously the G5 is still wired but it has new technology etc and the G7 is wireless but has a hefty price tag. So down to the serious question I play a lot of FPS games and am wondering if I would see an improvement with this laser technology? Also is it worth the extra £20 to go wireless with the G7?

Thanks

I would also like to know if the wireless mouse will suffer any lag in games? Also I don't think I am too worried about the batterys dieying on me as there is an indicator, unless this doesn't work to well?

Thanks for all your help finally decided to bite the bullet and ordered the G7 and a Dell 2405fpw Monitor

Man I hope these 2 things work out well or i can see some heafty postage returns happening lol.
