I know that for me this has been a slow process, but I haven't really had to crack a computer case in quite a while.
Looking for input before I pull the trigger on this one.
The link below is to an ASUS 660ti video card. I think this is the kepler core needed to keep up.

Reviews look good at newegg (from the gamers). LOL
I have a 460 watt power supply so that should be enough wattage. The card does require an additional power cable, it is just a matter of just which one. I think the ones in the case have different outputs from what I could tell.
