I know this topic has been beaten to death already, but please bear with me. I bought my card in May of this year, several months after the first reports of the GSOD/stripes surfaced. I was actually hoping AMD would address the issue in this time, but I guess not.
Did you guys ever come to a...
Obvious difference is reference design versus the "new" fan design. From reports I've read, only the reference models can have their firmware flashed to allow a higher voltage and thus a MUCH higher overclock.
Let's be honest guys - ATI really dealt a low-blow by first raising the MSRP of the 5850/5870, then undercutting to $260 with the 5830. Of course nVidia had to price their 470/480 relative to the 5850/5870 (don't ask me why the prices aren't identical), but they basically positioned their cards...
I know what you mean. I've got a 2y/o 8800GTS 640MB that I just can't justify retiring. I think my biggest obstacle is the price of entry for a new high-end card though. The 5850s are still about $30-40 more than I'd like.
Unless something has changed in the last several months, Fortron/FSP used to be one of the reputable brands in the game. Also, Corsair sources their PSUs from Seasonic, which is why I consider them "equal".
As far as PC Power & Cooling not making power supplies...
Good power supplies can be had for (relatively) cheap. Check out FSP Group - they make some of the best supplies out there, along with Corsair/Seasonic and PCP&C.
$40 for 400W
Which do I get? At most I'll probably be pushing ~500W with the following setup:
i7-920 @ 2.8-3.2GHz
I've read that PSUs are most efficient when total load is around 80%. That would mean I should get the TX650, right? But of course more is better and 750W would...
No, you (and I, and many others) misread what he posted. He's saying that with the rumored specs (shaders, processors, etc.), all you need to do is bump the core to 816MHz to beat a 5850. Considering it's allegedly at 750 already, it's a measly 66MHz bump to beat the next-highest card.
