go with an intel i3 2xxx processor and asrock extreme 3 gen3 z68 motherboard, much better for those titles. with what you save on the cost of the motherboard you could put in an even better i5 2xxx cpu. the motherboard i suggested still supports sli/crossfire and overclocking and PCIE3.
Battlefield you really want 6950+, skyrim only uses 2 cores anyways so the i3-2xxx isn't a bad idea, i believe in lightly threaded apps it performs similarly to i5 but i might be wrong. Micro-stuttering doesn't affect everyone though, got a mate using 2x6850 for battlefield on ultra and it runs very smoothly on his rig. 4gb 1600 ram is perfect cost/performance for gaming rigs atm. personally i'd try for i5-2xxx and 6950 if budget allowed.
