EXPLAIN.
they have changed the way the recent 6950's are made so flashing to 6970 cannot be done. you'll end up either bricking it or wasting your time (probably the first one)
I'll just have dual 6950's and be able to destroy any game out there. I think I am going to get an aftermarket cooler too and just make things cold so I can OC my CPU.
EDIT: 8gb RAM is freaking useless. I'll barely use 3GB at the most, if I need more, RAM is cheap as hell and I can pick some up with my rebate.
make sure you have a Mobo with dual x16 PCI-E slots then! (ones with a reduced bandwidth x16 PCI-E slots will severely reduce the speed of crossfire, to the point of making it a waste of money.)
also Xfireing a 6950 with a 6970 will underclock the 6970 to the 6950's speed, so i wouldn't try to get an increase in performance by buying a better GPU to Xfire with either, even if you can.
and if you do plan on playing crysis and other high spec games i would recommend going over 4GB of RAM. also if you plan on getting a reasonable amount of RAM then upgrading remember you will need to get the same type (preferably the exact same model if you can) which is why its better to buy in pairs/threes if your Mobo supports it.
