How good is AIDA64 Extreme actually? Its size is bigger than other PC audit softwares. Not to mention it's expensive. There are fine freewares on this genre, such as HWiNFO, CPU-Z, System Information for Windows Free, .etc. They all are smaller in size. I use SIW myself but the Technician's Edition which costs us $69,95 for lifetime updates. Compared with SIW Technician's Edition, paying $149,95 per year for AIDA64 Extreme (Engineer License) sounds unbelievable. Perhaps I should give AIDA64 a try to see if it is worth it.
