Will old MSI P-35 Audio onboard AC'97 work with MSI B85-G41?

Presently have : Intel Q6600 2.4/8GB DDR2 RAM/WIN7 64/Geforce 8600GT GPU/ Thermaltake 700W Toughpower PSU.
Will be updating to a MSI B85-G41 Mobo/16 DDR3 1600/ i7 4770 CPU/ keeping my PSU ( I was going to replace with a lower wattage, since alot of people told me to replace every 5-7 years, but it seems to be going strong. Also, I've heard that the Intel i7 IGP is better and supports more than the dedicated 8600GT GPU.

If you are familiar with AC'97 Audio codec on the 775 Socket MSI, and the newer B85-G41 has a ALC'887, codec, then is this going to be a problem with using the old top connectors?

Hello
NEW REBUILD~
Another thing about me using my old 7 year old CoolerMaster 690 ATX case, is that it presently has the 2 x.2.0 USB, Audio/Mic, eSata, and Firewire on top of the case. (I don't know anyone who uses the Firewire or eSata much) The Audio for this old Mobo (MSI P-35 Platinum 7345) originally came with AC'97 on the board.

If I get the MSI B85-G41 MoBo, it comes with both 2.0 USB (Front and back) and 3.0 USB (front and back) as well as the Audio/Mic, So hopefully, I can hook up the old 2.0 USB Top connector to the on board header, but will I still be able to use that top Audio/Mic and 2.0 USB's? Silly me, I thought I would have to go out and buy a newer case because of this.

Some folks say I would have to buy a Silverlake FP32B-E Bay connector to hook up Audio/Mic/2.0-3.0 USB. others tell me I could hook them right up to the board. I'm confused.

There are two standards for the FP_AUDIO header pinout: "AC'97", and "HD Audio" (also sometimes referred to by Intel's code name, "Azalia"). The two are not the same. Some motherboards, around the time of the transition, allow you to choose the pinout in the BIOS. Most don't. You have to look it up in the mobo manual, but most modern boards are all "HD Audio".

Most modern cases come with wiring for the front-panel headphone / mic jacks, with two pre-wired plugs, one labeled "AC'97", and one labeled "HD Audio".

You choose which one matches your mobo's pinout according to the manual, and/or set the BIOS setting properly.

If your case is older, and only includes AC'97 wiring, then if your mobo BIOS allows selecting that, then you are ok, otherwise, you cannot use your front-panel jacks.

Your case mfg may have an updated front-panel that could be ordered, especially if your case has been in production a long time.

If there's an adapter for connecting an older AC97 case's connectors to a modern motherboard's HD Audio port, I'm unaware of it. An updated case would seem to be the best solution.

All P35 chipset motherboards used High Definition Audio (HDA) codecs, not AC97. AC97 is like from the Intel 865/875 and maybe early Intel 910/915 days.

I had a MSI P35-Plantinum and it had a ALC888 chipset.

My new Asus Z87-A has a ALC887 chipset. I don't hear any difference.

The original CM 690 should support HD Audio (Azalia). Here's a photo from an old 2007 Hexus review. You can clearly see the cable tagged "Azalia".
