Hi folks. I am upgrading my system, but i need some advice. I am planning on upgrading to AsRock Z87-Extreme4 Mobo + Intel I5-4670K CPU. But I am unsure as to what PSU / Ram would be compatible. All-so i am planning on crossfiring my MSI 7870 OC ED. I know i should get a gtx 770 instead of a second GPU due to the crossfire microshuttering issues, but that simply isn't in my budget. In addition it seems AMD is working on some new frame-pacing drivers in order to fix, or at-least improve microshuttering. So anyway. . What PSU/Ram should i get? (I would prefer only to get 8GB of ram due to it being relatively cheap). Thanks in advance!
Edit: Speaking of microshuttering issues with crossfire. Do you guys think it would even be worth getting a second 7870 until we find out if the new frame-pacing drivers actually fix it?
