Yeah defiantly. When I only had 1 power cable connected to it I opened up Cod4 demo and I was totally unimpressed and thought buying this card was a big mistake. Now that it is running properly the difference is amazing and it runs really smoothly.
In my Nvidia settings, under color correction there is an option to turn up digital vibrance. Is this supposed to be put on max because it makes the colours really stand out, but seems excessively bright. I think I'm just used to using colours that weren't "digitally vibranted".
UT3 also seems to run at 2560 x 1600 with everything maxed; I really like this card
