Quote from Canoe007:
Sandybridge NOT = On-board Graphics
Well, the integrated on-die graphics aren't a big deal compared to the "enthusiast" graphic cards, but they're not the lack-luster on-board graphics we've all encountered and cringe when asked to fix for friends and family. Provided the integrated/MB has adequate outputs & resolution for your monitor(s), they should be more than adequate for the task of trading, and many more more-demanding tasks.
Where the integrated on-die graphics on the 2600K is a big deal, is it's speed so it gets the job done fast and more importantly, the CPU-GPU communication so that gets out of the way and lets the CPU fly and mange its resources.
Early reports my source (keep in mind he's tending to the extreme end of "enthusiast" - and that's not what his wife calls him) informed me of are that the Sandybridge (specifically the 2600K) gets the bulk of its benchmark from its resource sharing architecture, in structure, capability and its speed, with an additional significant benefit coming from the on-die graphics. Turning the on-die graphics off for a discrete graphics card removes that benefit and the benchmark suffers accordingly.
Like I said earlier: you'd be right for what we've seen before for on-board, but Sandybridge is game changing (at this point for non-enthusiast purposes); and, AMD 5800 (not 8700, don't know where I got that) series GPUs are expected out on-board 1336 MBs.
