Galaxy cards are great. I just want to point out, all reference cards are built by nvidia anyway - so if you're buying reference there's really no difference. I also like their GC overclocked cards quite a bit, although my favorites are usually the asus DC2 and msi lightning.
In terms of support, their support is excellent - their RMA turnarounds should you need to use it are VERY quick. I'm talking, within a week which is far better than what i've experienced with MSI and asus (2-3 months or longer). Their email and phone support is polite, professional, and actually speak english which is more than i can say for asus

. As an aside, when you call asus USA and their support gets mad at YOU for not speaking cantonese....what's wrong with that picture! Well, at least asus products are top notch - I've only had to use Asus support once in many, many years. I still like their stuff, because it's all very high quality.
Anyway, Galaxy is a relatively new name so they're not selling the volume that EVGA is, but that doesn't mean they're a bad company - I personally wouldn't hesitate to buy Galaxy for reference.
