Hi I was thinking of buying a Gigabyte HD 6850 at boxing day sale because of the dual fan. And luckily I got a deal in one of the local stores that's selling for $179.99, $10 (free shipping) cheaper than newegg and I was excited.
But then I saw a sale on the XFX HD 6870 for $229.99 so it's $24.74 cheaper $12.24 on shipping) than newegg.
If I also mail in the rebate I also get back $20! that means $44.74 cheaper. Looks like quite a good deal.
I am settling with getting a 6850 cause I heard ppl saying that 6850 can oc way better than 6870.
If I am going to OC, all 6850 brands are good, but unless you buy the MSI twin frozr (which costs like $270) for the 6870, all other brands don't oc very well. Given ocing at stock watts and assuming 6850 can oc 20% (775MHz -> 930MHz) and 6870 can oc 10% (900MHz -> 990MHz), I would choose $30 over the extra 60MHz. The pcts are estimates based on a review here:
