Well it's up to you to try that one that is most up-to-date and see if it helps, but is normally not recommended. Most of the time it will work, but just in case it has not work you will have to use the drivers provided from Dell.
My laptop from Acer has got the Intel Wireless card however, at own risk i tried using the drivers provided by Intel and till now it is working fine.
In general you should only use the drivers provided by the OEM, but provided you know what you are doing you can try the Intel but there is no guarantee that it will work.
Hope this will be useful.
