What do you know about the model of Peavey amp that you have? The Peavey Bandit, for example, is favored pretty highly for a solid state amp. A couple of pedals in front of that thing and you'd have a decent array of tones. Getting them into your PC is another matter, however.
This little unit makes a good amp simulator for going direct to a recording interface:

But it's bare-bones, no cool effects like overdrive/modulation/delay, etc built in. It's what you run your effects pedals INTO before going direct.
