Hi, I am new to Ubuntu and I would like to give Ubuntu 12.10 a try on my laptop. I am using an Acer Aspire 4530 laptop with the following specs:

AMD Turion X2 Dual Core processor 2.10GHz
NVidia GeForce 9100MG GPU

I am thinking of replacing my current Windows Vista OS(32-bit) with Ubuntu, so will it slow down my laptop? What type of hardware issues will I face after installing Ubuntu?
