Thanks for your reply but with all due respect to you, part of your post is rather hypocritical. The reason I say that is because you actually mention in one of your posts either on this forum or somewhere else, that you doubt whether updating the BIOS would do any good.
The BIOS update from XFX most likely won't fix anything. If you can get it to flash, great, if not, I wouldn't worry about it...

Unfortunately you took what I said in that thread out of context.
The original poster was looking at the XFX HD4870 BIOS to see if there was anything new or different in it compared to his current Sapphire HD4870 BIOS. While it would be possible to flash his Sapphire card with the XFX BIOS, I noted that there would likely be no difference at all, since the XFX HD4870 BIOS is merely a copy of what's already out there on other HD4870s.
A second poster, towards the end of the thread reported flickering problems that were not because of incorrectly set MEM clocks in the BIOS. I verified this by checking out his current BIOS, which he made available. The root cause is/was unknown but mainly due to overheating, unstable OC, driver/game incompatiblities, or some other unknown. With that regard, I mentioned that flashing his card with a fixed XFX HD4870 BIOS probably wouldn't solve his problems (flickering in-game in all games but Crysis). This problem rare to my knowledge, and something I wasn't able to diagnose.
...I also note that you say above, "A Few Bios Changes". Putting a graphics card in a slot is one thing but Bios changing a few times and reflashing the card is not something I have done before and no guarantee that it will work. The more I think about this, the more I am leaning toward just sending it back sealed and unopened within the seven day period for either an exchange or refund. Honestly, who needs the aggravation...
You'd only have to actually get the fixed BIOS, which is readily available (in these very forums), and flash the card once. You don't even need to edit the settings yourself, and is fairly simple to do in DOS or WINDOWS. This is a tried and true method, and does correctly fix the
specific 2D/3D MEM clock flashing problem. But obviously this isn't for everyone, and you seem to be hesistant on going down that path should the problem present itself. This is understandable..
...Anyway, it seems that even the ordinary standard non overclocked HD4870's may also be suffering from the dreaded flickering. I was hoping it was only the factory overclocked cards that had the problem.

There's a high probability that the OC'ed cards have this issue more frequently than non-OC'ed cards, only because the factory OC'ed cards need a BIOS with modified GPU/MEM settings. Any human intervention with the BIOS increases the chances, as some manufacturers still don't know, or are unaware of how to correctly set the MEM clocks to avoid this problem. Why or how these cards with improperly set BIOSes get past QC is beyond me, but it is and does happen.
That being said, as I stated before, it's not something permanent; it can be fixed. I just feel you're selling the card short, by not even considering trying it out. You paid a certain amount of money to get this XFX card (possibly more than the usual for an OC'ed HD4870), so you could at least give XFX and their "highly touted" customer service a shot, should you have problems with the card.
