I'm having a very nice gaming rig. I have Logitech G15 gaming keyboard, so having a gaming mouse would also be a great deal
Budget : 80$ max.
I've known about R.A.T. and G9
I guess both look good. R.A.T. have more cuztamizable options. I don't give a lot attention towards the DPI. The cuztamizability is cool anyways..
Also, I also do the internet surfing..
I have the Logitech G15 and G500 combination.. I don't however find it a major improvement over the MX 518.. I just loved the 518.. Its good looking, comfortable and very precise.. I don't think paying extra for any other mouse is worth it..
