I already have a Palit GTX 580 GPU (3 gb) and an original copy of Windows 7.
Gaming habits vary from MMO to FPS to indie, rarely fussed about eye watering graphics as a #1 priority but more keen on performance, speed and noise/heat levels. I plan to do a bit of streaming.
I'd like to spend no more than about £450-500 in total on mobo/case/ram/psu/cpu/hdd/cooling and any other bits I need to put it together, and would like to go for at least a 650w PSU to be safe as I'm paranoid about power issues after some bad experiences with my current setup!
I don't particularly intend to overclock nor add additional GPUs. I can't find much literature about this GPU so am struggling to find what components are most compatible. I'm very out of the loop!
