Hey guys I'm building a new PC for the first time. I I'm building the PC for gaming as well as some cpu/memory heavy tasks. For a GPU I'm almost definately going with the 6950. Thing only thing I'm worried about what is a better option. I could get the MSI HD Radeon 6950 Twin Frozr II and OC it, or I could get a reference XFX one and then flash the bios to a 6970.
My project specs are as follows to give an idea:
CPU: Intel i7-2600K (going to overclock)
CPU Cooler: Noctua NH-D14
RAM: Mushkin Enhanced Blackline 16GB 1600mhz DDR3 Ram(dual channel)
Case: Cooler Master 922 HAF
SSD: Crucial C300 Sata III 64gb SSD
HDD: 1TB Samsung Spinpoint F3
GPU: MSI Twin Frozr OC HD Radeon 6950
Motherboard: Gigabyte GA-P67A-UD4-B3
PSU: Corsair 850W Modular Power Supply
Personally i would go with the Twin Frozr II and O.C.I'm not to familair with the flashing BIOS technique and it isn't always a guanrteed thing.But if you've done your research and you know how to do it then by all means.
I purchased a Gigabyte reference 6950 card and flashed. No problems and once I OCed to 6970 specs it is now a beast. Not a bad deal. In the end it is up to you and if you are comfortable with 1) going thru the flashing process 2) you will be ok with it if it will not flash to the 6970 bios and you end up with a 6950 which is still a great card. FYI most but not all 6950s have a dual bio switch in case you run into issues.
