6770 CF vs 6950

post #1 of 22
Thread Starter 
Can't decide....

My board would support crossfire lovely, though my last experience left patchy driver support. (X1950 days..)

Pros of CF

2x 800 VS 1408 Processing Cores
Cheaper

Cons

Hotter, more power, drivers?

I feel I should play it safe and get the one 6950 but part of me wants to take the cheaper option!

definitely go with the HD6950, especially if you can find a reference model!

Why the reference model?

Also price difference is £70 (about $120)

Price difference too large, performance better on the cheaper solution. Go 2x6770.

Reference model 6950 has the option to unlock the disabled shader cores (1536), equaling the 6970 in shader performance, and you won't have to mess around with a crossfire profile ever! It's really worth the money.

Also a little worried about the vRAM as the 2GB on the 6950 is defiantly a safe bet for BF3

Performance is similar, it goes both ways depending on scaling more often favouring the 6770s. I would take the 6950 personally but if money is a big issue then 6770s are not a bad alternative.

I have a 5970 with 1GB frame buffer and I'm still not worried.. you shouldn't either unless you plan to run Eyefinity, however, 2GB of faster RAM won't hurt.

That would explain why the reference models are more expensive! Thought retailers had just gone crazy.
