Yeah, kinda. The g3258 was a gimmick at best. It'll run Windows stuff great, Web surfing, social media etc, even some games that are strong single thread like skyrim or fallout, but it bombs with multiple core games like gta-v or bf4 multi-player and due to complexity restraints of these ultra intense type games that's where the future is headed. In 3-4 years at best, by my reckoning, most of not all games will be 4 core optimized (8 core amd) and if you have anything less than an i5 sandy or fx8 series, you'll be in trouble. For the gpu, the 750ti was a great invention. The Maxwell gpus were a serious step in gpu technology, considering the average Joe pc can honestly get away with a 550w psu to power a 980ti beast, vrs the 1000w psu needed for top line cards a few years back. Great match for the g3258, never the less, its still the low end standard. Anything current is considerably better.
Behind, yes. Way behind? That'll be sometime next week.
