It's the IGPU. AMD's APU line completely and utterly trashes Intel's IGPUs. If you are looking at a value perspective, go ahead and get the A10. Just, if you plan on getting a graphics card later, the i5 would be the far superior option (supposing you get a 6670 or better)...Though, the 965 BE costs half that of the i5 2500k, and performs only 20% slower (That equates to, like, the 965 being 27% slower than the 3570K).
So yeah. A10.
Thank you for an un-biased answer.
I found almost none data about the benchmarks concerning image rendering where these two CPUs were put against via yahoo so do You have an idea how much faster i5 + 6670 would be compared to A10-5800K with integrated GPU in image rendering with Photoshop CS 6?? Considering A10-5800K would be half the price of i5 + 6670 combo...
