Which one would be better for gaming a Intel® Core™ i5-760 2.80 GHz 8M Intel Smart Cache LGA1156 or a Intel® Core™ i5-655K 3.20 GHz 4M Intel Smart Cache LGA 1156? Is it better to have more Ghz with less cache or less GHz and more cache?
Those are two very different CPUs. The i5 7xx line is a quad-core CPU, while the i5 6xx series are dual-cores. The difference in core count will have a much, much bigger difference in performance than any difference in cache size. I'd suggest the i5 760 personally as unless you are running some very old applications, you probably want at least 3-4 CPU cores in a machine today as many applications can use at least two CPU cores.
And about the GPU: the HD 5570 is a low-midrange card. It will let...
