DEAR LORD CELERON
Whole new build dude. Start from the ground up. Go for an i5-i7 or an A8-A10 processor, gtx 660 or +, OR 6850 + for the AMD style. At least 6 gb corsair vengeance, at least 500 gb HDD 7200 RPM (get at least a 64 gb SATA to boot the OS on to speed that shit UP). Meh I don't feel like thinking too much more, someone else can help further.
