advice needed as im only gonna game at 1920x1080 and i cant decide on a gtx780 or gtx780ti, also msi do a gtx780ti ref model, could i put the evga gtx780ti backplate on this or is the evga gtx780ti sc a better model, i want the ref model so the heat can blow out the back of the case, but i will watercool it but not just yet as still saving for the parts.
