Replacing drive in Dell 980 - bus speed question

Question is about a Dell 980 Optiplex computer running Windows 7 Pro.
The C drive has failed.   All I want to know is :
- The bus speed for the SATA drive in the Dell service manual says 1.5gb and 3.0 gb
- I purchased a Western Digital Blue WD10EZEX  1TB  7200 rpt 64mb cache SATA 6.0Gb/s internal drive.

What problems would I experience if I install this WD drive into the Dell?  
What needs to be done to enable a 6.0Gb/s drive to work with a computer having a bus speed of 3.0Gb/s?

Nothing.  It'll work at 3 Gb/s

SATA 3 Gbit/s and SATA 6 Gbit/s are compatible with each other. Most devices which are only SATA 3 Gbit/s can connect with devices that are SATA 6 Gbit/s, and vice versa, though SATA 3 Gbit/s devices only connect with SATA 6 Gbit/s devices at the slower 3 Gbit/s speed.

no problems you just can't use the full speed functionality of the drive

Not only is there no problem, but the drive will easily work at full speed.

A VERY tiny % of transfers to/from the drive happen at "interface speed"  (the SATA speed you referred to).    Well over 99% of transfer activity is at the actual sustained transfer rate of the drive ... i.e. how fast data can be written to or read from the platters => and this is FAR below the SATA II transfer speed (300MB/s) that the system supports.

The only time there'd be any real difference is if you were using an SSD ... and even then it'd be unlikely you would ever notice it.
