I have a very bad graphic card, I think It's a amd radeon 6450. I want to do a very big upgrade. I don't care about the money if it not goes more then 420$ but I still want the lowest price/power card. I wonder if I should go with the best, a 770 2g ( 350 $ ) , a 770 4g ( 400$ ), the 760 3g ( 285 $ ) or the 660ti 2g ( 250 ) ( 3g for 315$ ) I've made many research but I want the opinion of someone who have tested them. I have a i3 processor, 750w power supplies, 8gRAM and a pretty good motherboard. Tell me what you guys think about that please! I'm going to buy my new graphic card in one week. Remember that I want the best price/quality card, not necesary the best of them. Thanks.
