Hey guys, I want to expand my PC performance, current specs are: VGA: Geforce 780 ti 3GB Board: Z87X-UD5H-CF Ram: 16 GB DDR3 Processor: Core i5-4570 3.20 GHz The question is, if to get better VGA and render with GPU, or better set ram to 32 Gigs. If to get new VGA, what is the best performance? Is Vega good in GPU…
