I have a machine with a decent mobo, an i7 3770k and 8Gb ram @1600. Graphics are quite good with the integrated card.
I am about getting a dedicated graphics card but I don't know how to compare the IntelGraphics 4000 with the cards out there.
Just as example:
- The Sapphire 4850 is clocked ~700Mhz with 1GbDDR3 and 800 stream processors whilst
- The GT 630 is clocked at 810Mhz with 2GbDDR3 and 96 cuda cores
Using Intel's Extreme Tuning Utility I've found that IntelGraphics reaches 650Mhz while doing stuff.
Now there is the cores – stream processors issue. How is this compared to this chip?
Is there a way to compare my integrated graphics with other cards? Even in terms of performance, if not in terms of specs.

As a very rough comparison, have a look here: http://www.videocardbenchmark.net/video_lookup.php?gpu=Intel+HD+4000
According to that, a GTX 680 (for instance), is about 10x faster than your integrated graphics.
Your individual observed performance improvement will depend on many things. It's probably not 10x "better" for everyday use (since the benchmark is a bit synthetic) and you can probably do with a smaller card than the top-of-the-line one - but the chart should give you some idea on where the sweet spot is, comparing performance vs $.
I think it is safe to say that you will observe an improvement on graphics performance with a mid- or top-range graphics card, especially because the graphics performance is likely to be the bottleneck in your system.
