I am a noob at this..,so i only know Aida64 SP.., although no matter what other software u may use.., u will end up to HAVE to use a photo editing suite like PS.., if u want to venture in the world of creations.., i have a post with my SP in page 84.., along with some tutorial videos on how to make your own gauges..
Tbh.., Aida is great and i c no reason to try anything else.., as u can c in here.., you are limited only by your imagination..(ok and by lack of Photoshop use)..!!
If u do decide to try it out.., be prepared to invest a few nights.., but in the end u will be rewarded.., by the downloads u r gonna get when u post your job in here..!!
