Phc7006: In terms of transfer speed, a good HDD (samsung F1) reaches 25 mo/s, an hybrid (seagate momentus) 45 Mo/s and SSDs 100-175 Mo/s
xyem: I find it quite odd that no-one has said anything about this..
I get 80MiB/s on my HDDs...
That depends on the benchmark you use (read or write speeds, sequetial or blocks, larger or smaller blocks ) , whether your HDDs are in raid , whether you refer to peak rates or to average rates over an sustained period etc. For all clarity, the speed I mentionned come from one of the PC Mark.tests. My Velociraptor get 30 something in this test, where other benchmarks rate it at an average read speed of 100 something and a peak speed of 150 something
Eventually, the speeds above are meant to show the relative difference between the 3 techs . If you prefer, the PC mark indexes are in the lower 5000 for SSDs, in the 3000 for hybrid HDDs and in the 1500-2000 for HDDs
Phc7006: At least, with AMD APUs you get the possibility of Radeon dual graphics
Miaghstir: Unless they've changed it lately, the dedicated card doesn't support it if it's too good. Ie. only budget-line cards supports "hybrid crossfire", making the functionality quite redundant. If you get a decent card and want to squeeze a few more drops out of it by offloading some calculations to the built-in chip, you can't. If you get a low-end card you probably don't care enough, and won't hit the performance of the just slightly more expensive card running solo anyway.
Yes, but there is little point putting a top of the range GPU with an APU. A 38xx APU with a discrete 66xx Radeon gives you a cheap and solid system, not a top of the range gaming PC. If you want something better, you probably get a better CPU too. Anyway, even without a discrete GPU, the APU provides an acceptable acceleration.
Now, with Intel you either end up with an integrated GPU you will never use or a powerful and expensive CPU that gets limited by its integrated GPU. The gap in perf between the CPU and the GPU is indeed greater.

and on this more specifically, my experience ( on a laptop, so a faster GPU is not an option ) , Dual Graphics do improve FPS in DX10 games ( and make things worse in some older games )
