I'm not sure about their RMA policy in your country, but all the "manufacturers" of the GTX 295 at this time use the same cards (probably built by FOXCONN) with moderately tweaked BIOSes (mostly they put their company ID tag in there, and maybe mess a little with the memory and GPU settings on OC models, only heard of a BFG OC model so far) and personalised stickers and packaging.
What I mean is that all GTX 295 should be 99% identical (where it matters anyway).
Palit and all it's sister companies account for over 40% of all nVidia products on the market today. If they had a really bad RMA reputation, they wouldn't be there.
No, I don't work for them
... but 70 bucks off seems like a good deal. In my country I'm still waiting for them to go in stock (and they cost 535 EUR here, if you can imagine that).
