I can't say for certain if I will switch back to Intel but for now I'm loving AMD. Admittedly, my last rig had a lot of issues, but I think that had more to do with the power supply than anything else. This one I just built I'm working the kinks out of, but I like to push my systems as far as they will go and to hell with the consequences
I stick to AMD simply because of price. I built my current system for about $400, using a few left over parts from my old system (HD, CD-RW, case, monitor) and it does everything I need it to do and more. Intel makes some great stuff, and I wouldn't mind putting together an Intel box, but what I have will meet my needs for quite a while, and it was very inexpensive.
There are some annoyances with AMD (well, mostly VIA chipsets) but I'm so used to having computers with minor annoyances from both AMD and Intel that they really don't bother me anymore. All my Intel boxes were packard bell, HP, or compaq so obviously I've had my fair share of issues with both types of setups.
My setup is:
8k3a+ ($65 used)
XP 2100+ ($60 used)
Radeon 8500 (300/300, 9100 bios - $80 used)
SK-7 & TT-Smart Fan 2 (~$40)
TT Silent Purepower 420 w/ Active PFC (~$50)
256mb Winbond BH-5 pc3200 (~$40)
After shipping it all came out to about $400
Got it running 200x11 for 2200mhz, it'll go higher but at these speeds why bother. I simply couldn't have built something that performs this well without spending at least $100, probbably $200 more if I would have used intel.
