I still would rather not flash the 6970 bios, though
I wouldn't either.
I am willing to bet the unlock-rate is very low,as the original release cards with dual-bios switches are depleted.Since an overclocked 6950 can beat stock 6970's performance,just get the best overclocking GPU and forget about unlocking.

Ive used tools to see how much VRAM was in use during different games.
Crysis on max used 890MB

In game game, I touched over 1GB .. was using like 1100MB (Metro 2033).

thign thing is it seems most 2GB can overclock a bit higher...

i hit 1Ghz core and 1500 Mem without going over 41C on any of the GPU temps...

This is false.

They are just expensive, but there are TONS out there.

Here's the most objective answer you're gonna get:





These are all with 4x AA. In short, no difference. They do run out of Memory sometimes with 8x AA at 2560x1600 in some games, though, so if you run at that AA setting or at 5760x1080/1200, the 2GB version is the better choice.

At your current res with your current monitor, though, no difference at all.

you will be fine up to 1920 x 1200 res. More than that you might need more than 1GB. Check this chart out.

Unlocking the extra shaders isn't risky at all. Flashing is.
