I am looking for a build with gtx 970,I don't have a specific budget,I am looking for a pc powerful enough to run video editing softwares (After Effects,Nuke,Premiere) and also some 3D rendering.Components I already have Cooler Master Elite 431 plus cabinet,Samsung 128GB SSD,2x8Gb DDR3 ram,Corsair 450 watts power supply unit.Please suggest me the best gtx 970 variant, an Intel cpu (i7 would be ideal for my purpose I guess), ram and a motherboard. Also will a 450W psu be enough for this rig or will I need to upgrade.Thanks a lot.
