Intel makes better chipsets than AMD/Ati. I do not see the reason right now to go with AMD. All the older intel quads are priced really well against the AMDs.
Dunno how you can say that... AMD has a lot better-performing platform(s), especially in the budget sector, ATi IGPs can actually game, try Intel IGP... yaww right... in general, AMD seems to have much better budget offerings. I've seen energy-efficient 65W Phenom Quads going for AUD$220, considering that just about any other low-end quads (Q6600, Phenom X4 9550) cost
at least $300.
Oh and then they have those triple-cores... I got one because
-Athlon dual-cores are too inefficient, I wanted something that performs better clock-for-clock (Phenom I almost ties with Conroe/Kentsfield)
-Intel dual-core are too expensive, except for the low-end... and the low-end Intel CPUs don't have VT
-All quad-cores (including AMD) were just too expensive for my budget, I wanted a sub-$200 CPU.
A Phenom X3 fit perfectly withing my budget, it's a great low-cost multitasking CPU, and it comes with Virtualization... plus, Phenom 8x50 CPUs perform about as good as Intel's E8xxx/E7xxx series at a lower price (here in Australia anyways).
