Hello TSSG and welcome to Seven Forums.
Intel has many different series of graphics: 2500, 3000, 4000, etc. Some utilities will simply use the generic designation of "Intel Graphics Family" whenever they detect an Intel driver
rather than name a specific version.
When a company like Intel issues a driver, each computer manufacturer is free to customize that driver for their own line of computers. I suspect that Dell did exactly that for its line of Inspiron computers. Because the Intel driver has been customized by Dell, if you try to install the latest and greatest directly from Intel, it could seriously hose your computer. Quick short story:
About a year ago Intel and Windows Update said a new driver was available for my Intel HD 3000 Graphics. I installed it and immediately my Sony Vaio began crashing, hanging, and doing all kinds of weird stuff. Intel and Sony both told me the same thing: never use a non-customized driver if the computer manufacturer had done any modifications to the driver. It took Sony about 6 months to offer their own customized version of the driver. I installed it and haven't had any problems.
So my advice is to wait until Dell does its customizing and then, if you really, REALLY have to get the latest and greatest, get it from Dell. When it comes to drivers
, "if it ain't broke, don't fix it."
