What do you do, if gaming a higher speed gpu won't offer you literally a single 1% performance increase, a second 5850 would probably give you a 50-80% fps boost in the majority of games you play. Its an easy choice.
Frankly while they will be good cpu's and due to the pricing will push down prices on everything else, making them better value, they won't really offer much to any of the majority here who want gaming performance.
Next year we might see quite a few more games that push quad cores a little harder but throughout this year, other than a couple woeful GTA4 type console fubar ports, a 6 core isn't going to help.
Someone did a Metro2033 review and got the same minimum and average framerates on a 980x and a 965, with both at a range of speeds from 2 to 4Ghz, the 965 was actually faster at every speed, though the results were pretty much within 1FPS from 2Ghz to 4Ghz and on both platforms.
This year we're only likely to get more gpu limited games as more companies make dx11 games and "overuse" effects before the cards are ready for them.
For those who do 3d rendering and the like, a 6 core AMD chip for sub £150 would be a godsend, even more so if they still quite easily hit 4Ghz like current X4's(and unlocked x2's) on silent cooling.
