Hi! I am thinking of buying an mac pro 2009 or on eBay. What upgrades should i do? I want to run League of legends and i want to be a solid computer for day to day use. My budget is about 6-700$ and the computer costs 300$.
SSD drive. I also like my flashed Gigabyte GV-R797OC-3GD full supported by drivers. Look at RAM to be above 16GB (I have 48GB, but that's overkill unless you run VMs or certain graphics apps.)
Faster processors will only give you marginal improvement for games. Number of cores does not matter for most games.
