I'm going for a TriFire setup, R9 290, and would probably go for LCS since it gives amazing results but I got some options... 1 - 3 * CryVenom Cards, almost your typical R9 290 + EK block and EK backplate. 2 - 3 * Ref Cards, and add three of those and those 3 - 3 * best non Ref 290 out there - if it's better than Ref regarding stable OC and chocks, and their possible Blocks if there are any ones out there. I was going to regard TriSLI of GTX780 Classifieds from EVGA but I dunno would they scale better than AMD or not, and the clock speeds I can hit, what do you think guys? OR should I pick Dual 780 Tis now with LCS??? I'm much confused here..... 2560*1440 Gaming System, Core i7, 32GBs of RAM, 1250 Watt PSU.
