I'm thinking on upgrading my Sapphire 6850 to an Gtx 670 or a Sapphire 7970 and also changing my old 500w psu for a 750w one. But what I want to know is about my system getting bottleneck after I upgrade those two things.. (GPU and PSU). My new Gtx670 will work fine with my i3-2120? Also, if you guys have any suggestion for me (like changing RAM or changing my CPU) I would greatly appreciate it. Thank you for your patience and hope you guys can help me because I'm new on pc builds etc.
Much love, Grimly.
I will totally upgrade my PSU since it's pretty old now and I'm having some problems with it. I was also thinking on buying the 7950 since it is a lot cheaper than those two but, why do you recommend me buying it instead of a 7970/670?
