Currently I have an Intel i5-4670, ASRock Extreme 4 mobo, and a GTX 760 2GB (among all the other innards). I would really like to upgrade to a GTX 770 4GB but because of funds I can't upgrade from the 760 to the 770. (I can save...but who really wants to wait that long? ). A friend of mine said he would buy the CPU mobo and GPU from me for $550. (I just built the desktop about a month and a half ago because my 3 year old gaming laptop died). But I'm kind of sad that I can't run ultra quality graphics with texture packs on a couple games. While I am satisfied with the 760 and it is running flawlessly for me (other than the graphics thing), I would like to keep the total cost for CPU, mobo, and GPU under $600. I was looking at the FX-6300, but I'm not sure what mobo to partner it with. Or are there better CPU's or combos that would work more effectively with the 770 keeping under the $600 mark?
