170 for $280? Where?
I can get one off Newegg for roughly $220. I'm sure there are cheaper places out there, but th at's just off the top of my head.
The 165 is just as good if you're going to OC, it's around $160 if you can find one in stock.
Overall now I would have to say 4400, but I would get the 89w version. If you OC.
If you don't oc, the 4400 will suffice. Even though it's a relatively small 200mhz difference.
