Hello dear experts! Currently I am using GIGABYTE GTX 770 (2gb) OC with Core I5 2500 k overclocked to 4.2 Ghz / 8 GB of ram. I have purchased GTX 770 around a year and a half ago. So my question is should I upgrade to GIGABYTE GTX 970 G1 edition to play at 1080 p or wait till next NVIDIA release. I would like to stick with NVIDIA cards at the moment. The main issue from my perspective that now more games demand more than 2 Gb of video memory and honestly I am regretting that I didn't pick up GTX 770 with 4 Gb of memory onboard. Also I would like to mention that in my country GTX 970 G1 costs around 260 pounds (385 dollars). So if I would like to resell my GTX 770 I need to add around 130 pounds (190 dollars) for GTX 970. Is it worth it? Thanks for helping!
