I'd really like to play battlefield 4 on this desktop, is that possible? I do understand that I would need to up my PSU which is at 300w at the moment. I think I can get a decent video card and a 750w psu for around $100, or am I being hopeful? Just tired of the console and want to see the good stuff. I'd like to make a small purchase first, so I thought the card would be best.
