We know that merge PDF is a software that really merge multiple PDF files.
What if in a specific PDF you will edit 3 lines of text.
I think you'll need to use Foxit or Adobe products. (they can also merge multiple PDF files)
I choose ATI video cards, since I used for 2 years in studying 3D and CAD.
Also ATI GPU's is not for gaming only but also for designing such high quality of 3D rendered image.
Right now I don't have a twitter account.
I'll create tomorrow morning in my vacant time, Twitter is so popular.
Since I'm too busy right making some paperworks, I'll keep in touch in this forum
Thanks
