Here's what I recommend. It's a little over budget but it has everything you want and might want in the future. Do you plan to overclock? Also, skip the razer mouse and the Sidewinder keyboard, buy that keyboard I had in that, and go with this mouse, it's a fantastic little set.

That's my recommendation for a mouse over the Razer which your paying more for less.
