First off, anyone that says an i5 is no good for gaming has lost it.
An i7 is overkill for gaming. Photo/Video editing is a different story
Same for ram. 8GB is PLENTY for gaming. Again, editing is a different story.
With these 2 things in mind, here is my recommended build.
Intel Core i5-4690k $199
ASRock Z97 Extreme 4 Mobo $79 (when bundled with CPU)
Asus R9 290 4GB GPU $240
8GB Crucial DDR3 1600 Ram $70
Corsair CX750M PS $75
Thermaltake Commander $30
All for only....
$695 Before Taxes & After rebates
$755 without rebates applied
a little over$800 OTDafter tax, before rebates applied
this leaves you $200 to get your SSD, HDD and enough left over to upgrade either your CPU or ram a little more.
these are all prices that you can go pick up at MicroCenter tomorrow if you wanted to.
