My story:
Worked flawlessly with the Firepod and with the FF400.
At home I'm using my intern slot from my Gigabyte, it's imo TI, works also flawlessly(but same latency, so, no increase of performance).
I think that if it works from the start you'll be set with a VIA in the same way as with TI. I own my VIA for years and never had a problem.
Atleast overhere it's quite difficult to get a TI in a store(you have to order it) but you get a VIA for 10 bucks at every corner. TI is much more expensive.
Everyone recommends TI but atleast here VIA works.
