This card comes overclocked as the default from the maker.
It's an older card, but still quite powerful. It was top of the line when it was new, about 2-3 years ago.
Plays Skyrim on my system on high graphic details with no stuttering.
It's handled all the Source games maxed without any problems.
Plays Diablo 3 flawlessly.
It also comes with an awesome warranty from XFX (The maker). Lifetime transferable. So even if I/you sell/give the card away, then the lifetime warranty is still in effect. Lifetime warranty is just that, LIFETIME. Also the warranty expressly includes overclocking.
It is kind of a power-hungry card, so you will need at least a 500w power supply to handle it.
Also, when it has a minor overheating glitch, because of it's ridiculous clock speeds. The overheating is easily solved by either manually increasing the fan speed in the card control panel, or using the AMD Overdrive (which comes with the video card drivers) to throttle the speed just a little. (I reduced the clock speeds by 25 MHz and that solved it. (And even then it was STILL overclocked.))
All in all, it's a good card even still. The only reason that I'm selling it is because I just pimped out my rig with an even better video card. (An XFX Radeon 7970 Double-D Black)
Amazon lists the card with a new price starting at $150, and used starting at $100. I'm asking $100, and giving you the warranty transfer for it. I'm also willing to barter in trade if people have offers.
