What sort of problems?

According to this: http://www.sapphireforum.com/showthread.php?30866-Important-Information-Regarding-7870-and-quot-Black-Screen-quot-issues

If you pay attention to your model numbers you should be ok. Lots of people on OCN are happy with their cards, you have to remember that people only post in manufacturer forums when there is a problem, you don't hear about the good things.

7950 @ 1150/1500 (artifact free, playable) scores: 8321

This makes me wanna spend a day with the multimeter hooked up and work on restoring my 1200/6000 clocks for my 7950, in it's factory OC'd state, im easily gettting beat by overclocked 7870XTs now.


Factory OC is 900Mhz on my 7950 (preboost), however with summer coming, priority is on getting a water block on it, whether it be a custom loop, or a "Modded" Hxx Loop with the Trip Bracket.

once Im done with that I'll be back to running it as high as I can get it, or simply get another 7950 to XFire

I'm thinking about getting another Sapphire 7870 XT, and I have an older motherboard. I have to pick you guys' brain, I've got a P8P67 Le and looking up the specs this is what I see
1 x PCIe 2.0 x16 (blue) *1
1 x PCIe 2.0 x16 (x4 mode, black) *1

What does it mean when it says x4 mode? Also I have a 700 or 750 Watt PSU. Will that handle two cards?
Sorry, never crossfired before. How much of a difference will I notcie if I crossfire?

Thanks!
