Hey, I've been wondering about this for some time now. I used to play quite a lot of pc games a couple of years ago and my 8800gtx handled most games like a charm. However, lately my pc is used more and more to edit and convert videos. Using software with cuda accelleration did speed things up, but it's still frustrating to know that a 7:22 video takes over an hour to convert, regardless of which software I use. I have been looking into getting a gtx 570 or maybe something better than that, but I really would like to know a couple of things so I can convince my girlfriend to agree with the upgrade or maybe some more upgrades Would a more recent graphics cards improve conversion speed? Would upgrading my ram (4gb ddr3 1333mhz) to more capacity and higher clockspeed help much? Does sli boost cuda performance much?
