Do I need ASIO for Windows 7 ?

I am on Windows XP with Foobar.
I was wanting to try to move to Windows 7.
Is that 'recommended' ?
I use only computer for playback.
I am very happy with Foobar & XP.
Not very literate with computers & hence an a bit paranoid.
Suggestions would be appreciated.
DAC's used are Ayon Skylla & dCS Scarlatti [3 box] & DAD AX24.
Thanks,
Appreciate the feedback.

Hello Pkubica !
Thanks for the reply;
The hardware in not an issue at all.
When I use a dCS Scarlatti, to make a new Server is 'pittens'
So cost is not an issue.
I could use the same Antec housing & Power Supply & change the Mother Board & Processor.
The million $ question is, what 'sounds' better ?
Windows 7 with Wasapi or XP with ASIO ?
I need to know sq & that is all that matters.....
Software in India is 'cheap' and rather easily available.
So having both installed on the [same] machine too is a possibility [boot them separately].

Suggestions & Observations would be much appreciated.

Thanks Larry & Pkubica.
With a dCS Scarlatti, I can only play 16/44.
The Scarlatti does not accept more than that on USB.
My earlier Weiss Minerva used to accept & play 24/192. But that is gone.
I use foobar & prefer Flac to Wave [metadata].
However, I still have a bit of wave on my server.
