It hardly matters... even Steve Walton just compared the latest GeForce 310.61 update, against Catalyst 12.11 beta drivers and you can see the results.

On the first page Steve said "Around the same time, Nvidia released a new beta driver of its own (GeForce 310.33) which claimed modest gains for the GTX 680 and GTX 660 in several titles, and this driver has since been replaced by the GeForce 310.61 update, which made further performance enhancements. This is what we'll be testing today."
While in conclusion said... "At 1920x1200 the GeForce GTX 670 is 12% faster than
(referance) 7950, and just 2% faster than the 7950 with Boost
(almost indentical to W1zzards' here). However the GTX 670 is 27% more expensive than both cards, so whichever way you slice it the Radeon HD 7950 Boost is the better proposition and things just get worse for the GTX 670 as the resolution is increased."
Now I'm not defending W1zzard (while not a fan of Steve) but it takes a bunch of time to re-run all testing and collect date for minimal differences. That said, I like to see after initial release reviews of a new series, which should show the new card as it sit in the past-present line up with the released drivers. Although when a card like this comes along I’d like to see just those cards in competition and in the current price structure. I'd hope for a more of a concise snap-shot of the market today, but even that’s hard.
I mean if we (like Steve found) looking at current market pricing would you compare this to a GTX 670? Today for most good comparative quality builds are $360-390 –AR or like 25% more cost (identical performance @1920x) than the bulk of 7950 Boost models of this quality which are $280-310. Sure as the member above indicated, Egg price (No Rebate) is higher than W1zzard posted, but knowing what we know this HIS… will get with the program quickly with a rebate.
Heck in price 7950 Boost models are very much competitive with more the 660Ti that price in around $270-290 after rebates. So paying about 10% more for a 7950 Boost yeilds a 15% in Fps that the real take away!
