Thanks all for helping me. To be more clear, the applications I generally use my PC for is all MS Office Applications, Adobe Premier, Photoshop, Acrobat, Designer and also customized Business and Accounting Softwares. In addition to that I also use AUTOCAD and CorelDRAW X3 and / or equivalent softwares. I also do a lot of Internet Surfing with multiple browsers open and multiple tabs in each browser open simultaneously. Can you please suggest me a suitable processor for these tasks both in INTEL and AMD?.
what is your budget?
for multi-tasking and CAD, you'd benefit from a tri-core or higher with a good amount of ram. if you don't overclock your cpu then a core i5 2400 and higher with 8+ gb ram would be good for you. from amd's side, you have older ph ii x3, x4, x6 cpus, and newer fx 41xx, 61xx, 81xx to choose from. amd's cpus usually consume more power than intel's. current fx cpus use more power than their intel counterparts.
