Hey guys, never really used this forum before, but I finally have a good reason to. I'm planning to replace the graphics card in my prebuilt ASUS M51BC. It came stock with an AMD-FX 8300 8-core and an NVIDIA GTX 650. I've been considering upgrading to a GTX 760, but since I've never really opened my computer up before, I don't know what to do or what to expect. I'm not sure if the power supply will handle it, if the motherboard is supported, and I'm also confused on all the different models listed here on NVIDIA's website: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-760/buy-gpu Thanks to anyone who can give me a head start here, or even recommendations toward another card
