Kyle I know you want the card to be as cheap as everyone else does but the fact of the matter and from my experience they will be charging upwards of £250 for the 1GB. Simple as.
That's what I don't get though, it's got nothing to do with me wanting them to be as cheap as possible. You're telling me that your experience says they're going to be upwards of £250? I could afford to pay £250 for them, but that's not the point at all. I was saying this about the 4850s, look what happened?
Your experience
doesn't tell you that, you tell yourself that, regardless of the evidence that's out there and the previous releases from ATi (which is what you would use to base your experience, but you're not).
As I keep saying, over again, the 512MBs are reportedly going to be $299 down from $329.
Talking of experience, what your experience
should tell you is that the 4850s are $199, over here, they're the same plus VAT.
The 4870, said to be $299, there's no reason why it will be any different to the 4850.
So now, the 4870 1GB, you actually think that they're going to be an additional $180-200?

That's terribly shocking that you think your experience points to that being the case.
Since the 3800s came out, ATi has promised to keep their cards at under $499. The 1GBs are not reference, as far as I know, but if they're going to be charging $500 for a 1GB 4870, where does the 4870X2 come in to it?
You experience should tell you that based on the 3870X2, it'll be under $500, in accordance to ATi's 'promise'.
Why would ATi have two graphics cards at the same price point, but with radically different performance?
As I keep having to say, the 512MB 4870s will be around £180 in accordance to the 4850's price, and the stated 4870 US price. They aren't going to add another £80-100 for an extra 512MB GDDR RAM. The price difference between the 4850 and 4870 is about £50-60, which is right.
For that extra £50-60, you get 100Mhz on the core speed, GDDR5 RAM, Dual slot cooler with heatpipes, and an overall more powerful graphics card. So your extra £80-100 doesn't make any sense at all for just extra RAM what ever way you look at it.
Now if they do end up being this price, which I highly doubt, then they're going against their current trends completely. Which, I'm sure they know, won't buy them any customers, and we all know they need as many customers as they can get.
