Hi, I was thinking of uprading my pc, at the moment i'm using AMD 64 3500 with asus A8N SLI motherboard I am not sure weather to upgrade my AMD or go for Intel. I have been a fan of AMD's for a long time but it look as if intel are way ahead at the moment. please share me your views thanks

my views are: why do you feel you need to upgrade, what do you need to do on the PC that a new one will do better then your existing pc?

I do alot of multi tasking like encoding video files and with the amd 64 3500 it doesnt give me enough resorces to run it properly and at times computer freezes because of it

If you insist on multitasking while encoding video, consider getting a dual core CPU...either an Opteron or an X2. More RAM wouldn't hurt either. But if your system locks up, it's not because the CPU/board combo is too weak, it's because you have some sort of problem with either your settings, software, or hardware.

back to my point, which one is the better choice AMD athlon dual core or Intel core 2 due ?

"which one is the better choice AMD athlon dual core or Intel core 2 due" If you're willing to shell out $500+ for a new motherboard, CPU, & RAM, plus go thru the hassle of reinstalling Windows, device drivers, etc, then the Core 2 Duo is the better choice. If it was me, the 1st thing I'd do is find out why the system is freezing up & fix it. But if you feel you need a dual-core CPU to be able to multi-task & don't wanna spend $500+, consider getting something like an A64 X2 4400+ or Opteron 170 for under $200 & just slap it in your current board.
