Is PC fast enough for DVS7??

I have a PC with an AMD Athlon XP 1800+ 1.5 GHz processor, and 1 GB of ram. Can anybody tell me if this will be enough to run DVS7 ? I plan to use the vinyl timecode and like to scratch. Also I was looking at a laptop today that has a 2.8GHz Pentium 4 HT processor with 1GB of RAM. I'm pretty sure that the processor on the laptop would keep up but am leery of the 1GB RAM memory. Does anybody have any experience with my PC specs and performance, or possible laptop specs.??? Thanks for helping....Peace!
