I have personally owned 4 eVGA boards and they were trouble-free. I have also read only praise here for both vendors. If there's any chance you'll want something better soon however, eVGA has their "step-up" program which allows you to trade-in your card once, within 90 days, for a better one and pay only the difference in MSRP between them.
thx for the replies and I like the MSI 9600GT but it's not in stock in the store near my home. They are offering a stock XFX and Zotac, and overclocked eVGA and Asus boards. I forget about Asus since the heatsink is crappy.
The cards got the same reference cooler and I think will perform on par with each other so I'll pick whatever is the cheapest when I'll get there next friday. Thanks guys
