LOL, the actual price point for the 5850 would be the MSRP of $259. If you can get THAT, it's a hell of a deal today. Which really ticks me off, cause I could have bought them at release those 6 months or so ago for that price but decided to wait for the price to "go down" and that was a mistake. It can still be picked up for about $259 but only after coupons and incentives like bing cashback.
Tigerdirect has some 5850's around $300 and typically has a 10% to 15% cashback on any given day. Just make sure if you go that route you take screenshots with every step of the transaction just to make sure you get your bing cashback.
But basically, I think the general consensus is still this.
If you a considering a 5850, 470, or 5870 it all comes down to price. If you have the cash the 5870 is still the best although when max overclocks are taken it's performance lead is not really that much more than the other two cards at around 5% or so more performance.
Which means, if you want the best bang for the buck, the 5850 is the card to get. Especially if you overclock. If you get a nice lucky chip, it may damn near equal the performance of most overclocked 5870s.
The only reasons to go with the 470 is if you somehow found a phenomenal deal on one to make it the same price as a 5850, or you actually regularly play one of the few games with hard Physx accelerations and like Physx in the game, or if you are just a die nvidia fan.
Not saying the 470 is not a bad card, but when compared to the competition, the cons generally outweigh the pros.
