PCIe slot compatible FW card

I'm in the early stages of  buying the parts for a new build and I am committed to 2011-v3 since I already have an Intel 5820K Haswell. I'm currently using a firewire interface with TI chipset that is working flawless on my current setup. FW seems to be going away as a connection on any MOBO so I'm looking at possibly buying a card to get a few more years out of my Presonus firestudio tube interface. It's either that or spend more money on another usb 2.0 interface . I don't see anything that's PCIe 1 or 2 that is TI based. My old card is PCi and has the compatible TI chipset.
Any recommendations on a card that will help me keep my old interface awhile longer? Additionally I would hope that there's still a driver around to help me use it with Win 10. I hate to gamble and simply buy a card with no prior info ..
Don't know if this matters but I plan to O.C.

Thanks Wookie! Looks like the thing I need.

Yes the 4790K is more than formidable for most anything and is less expensive considering all of the other additions you need to upgrade. The only advantages to the 2011-v3 are mostly future proofing ,more lanes and cores, but those advantages don't mean much for a smaller project. If I had known that the extra expense was involved I might have gone with 4790K and not cared about " future proofing". The 4790K will be a strong contender for a long time.
