I've been looking into getting a new GPU recently and one that has caught my eye is the vapor x 5870. The card is listed shown here http://overclockers.co.uk/showprod [...] =GX-230-SP
It looks appealing to me, especially since it keeps so cool, but I'm wondering, will I be able to OC it with some downloadable OC utilities? I've read that the ATi tweak tool doesn't allow you to stretch far, and I'd like to do some stretching since it's been known to stay about 15-20 C cooler then the reference card.
If there are some OC utilities I can use, what are some good ones? What performance gains can I expect from OCing it?
You can OC within CCC, of course. Tools becoming more popular for OC'ing because they allow adjustments to voltages and permit clocks beyond ATI recommended limits are also available.
AMD GPU Clock Tool, MSI Afterburner, and Radeon BIOS Editor are available. Typically, you'll need to use two of the tools in combination, then use Furmark and/or Unigine Heaven to test stability. As far as performance gains, that all depends on the card's ability to function with a really aggressive or beyond spec OC. It also depends on the game titles in question. Basically, it's an age-old question - do the ends justify the means?
No idea. It's listed on the USA website as "NEW!" like it's available, but I've not seen any e-tailer or retailer listing it, yet. I'm aware of it's specs, though. I honestly can't believe they're using a 15-phase design. I thought 5+2 was a lot, but 15?! Wow...
