I have an older system and I am looking to up grade my video card. My question is that if the bottle neck of the older system is worth the upgrade on the video card. I currently have an EVGA 780i FTW mother, E8400 processer overclocked to 3.75, 4GB of ram at 800Mhz, and want to replace the EVGA gtx 260 core 216 with a new card I would like to get a 770 and later build a new system around that when I get the money which will be good amount of time.
