Your on the right lines, but use a haswell i3 4130 processor, and an asus h81 motherboard.
This is amazingly better for games. Never use an MSI motherboard, untrustworthy company..
You want 4 gig of cheap cas 11 ram that runs at 1.5 volts. More expense is wasted.
Haswell 4130's are not stable in price yet, but almost eradicate the sticky frame bits in games.
Talks of over 60 frames are irrelevant. You monitor runs at 60 frames per second. The haswell chip
works best keeping the bottom up, not the top that doesnt matter.
